Description

化學強化用玻璃及玻璃框體 Glass and glass frame for chemical strengthening 發明領域 Field of invention

本發明係有關於一種使用於電子機器、例如可攜帶使用之通訊機器及資訊處理裝置等之框體等的化學強化用玻璃，以及使用了如所述之化學強化用玻璃的玻璃框體。 The present invention relates to a glass for chemical strengthening used in an electronic device, for example, a casing for carrying a communication device and an information processing device, and the like, and a glass frame using the glass for chemical strengthening as described above.

發明背景 Background of the invention

以往，對於行動電話等之可攜帶使用之通訊機器及資訊處理裝置之框體的材料，考量到設計性、刮痕抗性、可加工性及成本等，而主要使用樹脂或者係金屬。然而，近來，在所述之樹脂及金屬之外，還嘗試加入了迄今未被使用過的玻璃來作為框體材料使用(例如，參照專利文獻1)。而推測係藉由使用玻璃可賦予具有透明感之獨特的裝飾效果之故。 In the past, the materials of the frame of the communication device and the information processing device that can be used for mobile phones and the like have been considered to be design, scratch resistance, workability, cost, etc., and resin or metal is mainly used. However, recently, in addition to the above-mentioned resins and metals, attempts have been made to add glass which has not been used so far as a frame material (for example, refer to Patent Document 1). It is speculated that the use of glass can impart a unique decorative effect with transparency.

然而，一般而言玻璃係脆弱的，且另一方面，使用於行動電話等之電子機器的框體，由其使用形態而言，係被要求有可充分承受因使用時之掉落撞擊所造成之破損亦或是因長期使用所致之接觸損傷等的高強度。因此，而尋求具有可使用於行動電話等之電子機器的框體之高強度的玻璃。 However, in general, the glass is fragile, and on the other hand, the frame of an electronic device used for a mobile phone or the like is required to be sufficiently resistant to falling impact due to use. The damage is also high strength due to contact damage caused by long-term use. Therefore, it is sought to have a high-strength glass having a casing that can be used for an electronic device such as a mobile phone.

提高玻璃強度之技術有各種為人所知悉。而其代表性的方法係：藉由送風冷卻等，將業已加熱至軟化點附近的玻璃板表面急速地冷卻，而使於表面形成壓縮應力層 的方法(風冷強化法/物理強化法)；以及在玻璃轉移點以下之溫度下，藉由離子交換，將玻璃板表面之離子半徑小的鹼金屬離子(典型的係Li離子、Na離子)交換成離子半徑較大的鹼金屬離子(典型的係對Li離子為Na離子或K離子，而對Na離子則為K離子)，而於玻璃表面形成壓縮應力層的方法(化學強化法)。其皆係藉由於玻璃的表面形成壓縮應力層而使強度提升者。 There are various techniques for increasing the strength of glass. The representative method is that the surface of the glass plate which has been heated to near the softening point is rapidly cooled by air cooling or the like, and a compressive stress layer is formed on the surface. Method (air-cooling strengthening method/physical strengthening method); and alkali metal ions (typically Li ions, Na ions) having a small ionic radius on the surface of the glass plate by ion exchange at a temperature below the glass transition point It is exchanged into a method of forming a compressive stress layer on the surface of an alkali metal ion (a typical pair of Li ions is a Na ion or a K ion for a Na ion or a K ion for a Na ion) (chemical strengthening method). Both of them increase the strength by forming a compressive stress layer on the surface of the glass.

而於該等之方法中，前者之風冷強化法若像前述框體用玻璃般玻璃的厚度薄(通常為3mm以下)的話，則會因表面與內部之溫度差難產生而難以形成壓縮應力層。並且，由於冷卻溫度不一，為薄的玻璃板時會有平面性受損之虞。相對於此，後者之化學強化法，則即便為薄的玻璃板亦可使於表面形成壓縮應力層，且不會有平面性受損的情形。因此，用於前述框體之玻璃係宜為可藉由化學強化法來強化的材料。 In the above methods, if the air-cooling strengthening method of the former is thinner than the glass-like glass of the frame (usually 3 mm or less), it is difficult to form a compressive stress due to a temperature difference between the surface and the inside. Floor. Moreover, since the cooling temperature is not uniform, there is a flatness damage when it is a thin glass plate. On the other hand, in the latter chemical strengthening method, even if it is a thin glass plate, a compressive stress layer can be formed on the surface, and the planarity will not be damaged. Therefore, the glass used for the above-mentioned frame is preferably a material which can be strengthened by a chemical strengthening method.

發明概要 Summary of invention

行動電話等之電子機器的框體因尋求高設計性，故將玻璃本身予以著色來使用，亦即想出使用含有著色劑的玻璃。 Since the casing of an electronic device such as a mobile phone is designed to be highly designed, the glass itself is colored and used, that is, a glass containing a coloring agent is used.

然而，若想對如所述之含有著色劑的玻璃適用前述之化學強化法來進行強化的話，將其與已使不含著色劑的玻璃進行了化學強化的情況相比，則較難進行化學強化，即已確認含有著色劑之化學強化玻璃的強度，與不含著色劑之化學強化玻璃相比相對上係較低的。而其要因，可推測係：藉由使含有著色劑，而使因離子交換而被取代成離子半徑大的鹼金屬離子之小的鹼金屬離子於玻璃中的含量相對地變少、或被離子交換的量減少，以及由於著色離子的存在而妨礙了鹼金屬離子的移動等。 However, if the above-mentioned chemical strengthening method is used for strengthening the glass containing the coloring agent as described above, it is more difficult to perform chemistry than the case where the glass containing no coloring agent is chemically strengthened. The strengthening, that is, the strength of the chemically strengthened glass containing the coloring agent has been confirmed to be relatively lower than that of the chemically strengthened glass containing no coloring agent. However, it is presumed that the content of the alkali metal ion which is substituted by the ion exchange to the alkali metal ion having a large ionic radius in the glass is relatively small or is ionized by the inclusion of the coloring agent. The amount of exchange is reduced, and the movement of alkali metal ions or the like is hindered due to the presence of colored ions.

又，玻璃之著色係藉由使過渡金屬於特定之價態下存在於玻璃中，而使之呈現所需求的顯色。然而，若將玻璃長期使用於框體等上，則會因紫外線等的影響造成過渡金屬之價態改變而使玻璃的顏色發生變化，即有發生所謂的「曝晒作用(solarization)」的情況。因此，用於框體之著色玻璃係被期望可長期維持一開始之著色狀態，而不會由於顏色的變化損及設計性。 Moreover, the color of the glass is rendered in the desired color by allowing the transition metal to be present in the glass in a particular valence state. However, when the glass is used for a long period of time on a frame or the like, the color of the transition metal changes due to the influence of ultraviolet rays or the like, and the color of the glass changes, that is, a so-called "solarization" occurs. Therefore, the colored glass used for the frame is expected to maintain the initial coloring state for a long period of time without impairing the design property due to the change in color.

本發明係以提供一種強度高，且即便長期使用所造成之顏色變化亦少，且可獲得耐曝晒作用性高的玻璃之化學強化用玻璃，以及使用了所述之化學強化用玻璃之框體為目的。 The present invention provides a glass for chemical strengthening which has high strength and which has little color change due to long-term use, and which can obtain glass having high exposure resistance, and a frame using the chemical strengthening glass. for purpose.

用以實施發明之形態 Form for implementing the invention

以下，將就本發明之實施形態予以說明。 Hereinafter, embodiments of the present invention will be described.

(第1實施形態) (First embodiment)

首先，將就本發明化學強化用玻璃1之第1實施形態的化學強化用玻璃予以說明。另外，對於本實施形態及自此以後所說明之實施形態，於其中之玻璃組成的說明只要無特別之註明，即使用換算成下述氧化物之莫耳%表示含量來進行。以下「莫耳%」亦僅標示為「%」。 First, the glass for chemical strengthening according to the first embodiment of the glass for chemical strengthening according to the present invention will be described. In addition, in the embodiment and the embodiment described hereinafter, the description of the glass composition therein is carried out by using the content of mol% expressed as the following oxide, unless otherwise specified. The following "% of Moer" is also only marked as "%".

第1實施形態之化學強化用玻璃係含有SiO2、Al2O3、Na2O、Fe2O3、TiO2，及為著色成分之MpOq(但是，M係選自Co、Cu、V、Cr、Pr、Ce、Bi、Eu、Mn、Er、Ni、Nd、W、Rb、Sn及Ag中之至少一種，且p與q係M與O之原子比)作為必要成分者。 The glass for chemical strengthening according to the first embodiment contains SiO 2 , Al 2 O 3 , Na 2 O, Fe 2 O 3 , TiO 2 , and MpOq which is a coloring component (however, M is selected from Co, Cu, V, and At least one of Cr, Pr, Ce, Bi, Eu, Mn, Er, Ni, Nd, W, Rb, Sn, and Ag, and the atomic ratio of p to the q system M to O is an essential component.

該第1實施形態之化學強化用玻璃的組成係如下：SiO2：55~80%、Al2O3：3~16%、Na2O：5~16%、Fe2O3：0.001~3%、TiO2：0.001~3%、MpOq：0.001~10%(但是，M係選自Co、Cu、V、Cr、Pr、Ce、Bi、Eu、Mn、Er、Ni、Nd、W及Ag中之至少一種，且p與q係M與O之原子比)、B2O3：0~12%、K2O：0~5%、MgO：0~15%、ZnO：0~5%、ZrO2：0~5%、及RO：0~1%(但是，R係選自Sr、Ba及Ca中之至少一種)。 The composition of the chemical strengthening glass according to the first embodiment is as follows: SiO 2 : 55 to 80%, Al 2 O 3 : 3 to 16%, Na 2 O: 5 to 16%, and Fe 2 O 3 : 0.001 to 3 %, TiO 2 : 0.001 to 3%, MpOq: 0.001 to 10% (however, M is selected from the group consisting of Co, Cu, V, Cr, Pr, Ce, Bi, Eu, Mn, Er, Ni, Nd, W, and Ag) At least one of them, and the atomic ratio of p to q between M and O), B 2 O 3 : 0 to 12%, K 2 O: 0 to 5%, MgO: 0 to 15%, and ZnO: 0 to 5% ZrO 2 : 0 to 5%, and RO: 0 to 1% (however, R is selected from at least one of Sr, Ba, and Ca).

為本實施形態之化學強化用玻璃之必要成分的SiO2，係構成玻璃骨架之成分。若其含量小於55%，作為玻璃的穩定性可能會降低，或者是耐氣候性會降低。因此，而使含有55%以上。且宜為58%以上，而較佳係60%以上。 又，若其含量超過80%則玻璃的黏性會增大而熔融性會降低。因此，其含量係令為80%以下。且宜為78%以下，較佳則係75%以下。 SiO 2 which is an essential component of the glass for chemical strengthening of the present embodiment constitutes a component of the glass skeleton. If the content is less than 55%, the stability as glass may be lowered, or the weather resistance may be lowered. Therefore, it contains 55% or more. And it is preferably 58% or more, and more preferably 60% or more. Moreover, if the content exceeds 80%, the viscosity of the glass increases and the meltability decreases. Therefore, the content is 80% or less. It is preferably 78% or less, preferably 75% or less.

Al2O3係使玻璃的耐氣候性提升之成分。若其含量小於3%則耐氣候性會降低。因此，而使含有3%以上。且宜為4%以上，較佳則係5%以上。又，若其含量超過16%，則玻璃的黏性會變高而均質的熔融會變得困難。因此，其含量係令為16%以下。且宜為14%以下，較佳則係12%以下。 Al 2 O 3 is a component that enhances the weather resistance of glass. If the content is less than 3%, the weather resistance will be lowered. Therefore, it contains 3% or more. And it is preferably 4% or more, and preferably 5% or more. Moreover, when the content exceeds 16%, the viscosity of the glass becomes high, and homogeneous melting becomes difficult. Therefore, the content is such that it is 16% or less. It is preferably 14% or less, preferably 12% or less.

Na2O不但係使玻璃的熔融性提升之成分，同時亦係用以藉由離子交換而使形成壓縮應力層於玻璃表面上的必要成分。若其含量小於5%則熔融性會降低，而且會變得難以藉由離子交換而於玻璃表面上形成所需之壓縮應力層。因此，而使含有5%以上。且宜為6%以上，較佳則係8%以上。又，若其含量超過16%則耐氣候性會降低。因此，其含量係令為16%以下。且宜為15%以下，較佳則係14%以下。 Na 2 O is not only a component that enhances the meltability of the glass, but also an essential component for forming a compressive stress layer on the surface of the glass by ion exchange. If the content is less than 5%, the meltability is lowered, and it becomes difficult to form a desired compressive stress layer on the surface of the glass by ion exchange. Therefore, it contains 5% or more. It is preferably 6% or more, preferably 8% or more. Moreover, if the content exceeds 16%, the weather resistance will be lowered. Therefore, the content is such that it is 16% or less. It is preferably 15% or less, preferably 14% or less.

Fe2O3係使玻璃中之離子的移動容易而促進離子交換的成分。若其含量小於0.001%則無法獲得促進離子交換效果。因此，而使含有0.001%以上。且宜為0.01%以上，較佳則係0.03%以上。又，若其含量超過3%則玻璃會變得不穩定而容易發生失透明。因此，其含量係令為3%以下。且宜為2.8%以下，較佳則係2.5%以下。 Fe 2 O 3 is a component that facilitates the movement of ions in the glass and promotes ion exchange. If the content is less than 0.001%, the effect of promoting ion exchange cannot be obtained. Therefore, it is contained in an amount of 0.001% or more. It is preferably 0.01% or more, preferably 0.03% or more. Moreover, if the content exceeds 3%, the glass becomes unstable and the loss of transparency tends to occur. Therefore, the content is 3% or less. It is preferably 2.8% or less, preferably 2.5% or less.

再者，藉由添加Fe2O3可促進離子交換，係推測因玻璃中存在著4配位之Fe3+，而使玻璃中之非架橋氧成為 架橋氧，結果因負的電荷密度變低，而使Na+離子變得容易活動所致。 Furthermore, ion exchange can be promoted by the addition of Fe 2 O 3 , which is presumed to be due to the presence of 4-coordinated Fe 3+ in the glass, so that the non-bridging oxygen in the glass becomes bridging oxygen, resulting in a low negative charge density. And make Na + ions become easy to move.

Fe2O3係依據Fe離子之價態來賦予玻璃黄色或者係綠色的色彩。於Fe2+的情況時係綠色~藍綠色，而於Fe3+的情況時則係成為黄色。本發明之大特徵，即對於化學強化的促進係以Fe3+之狀態為宜，且以可氧化性來熔融為理想，但通常在玻璃中Fe2+與Fe3+係共存的，故無法全部皆為Fe3+之狀態。因此，於Fe2O3之含量多的情況時會有出現少量存在之Fe2+的顏色的情況，此時，為了顯示出呈現綠色，亦可將Fe2O3與前述之綠色的著色劑併用。又因Fe3+而呈現出的黄色雖淡，但以相同之想法而言亦可將Fe2O3與前述之黄色的著色劑併用。 Fe 2 O 3 imparts a yellowish or greenish color depending on the valence state of the Fe ions. Fe-based green to blue-green when the case ~ 2+, Fe 3+ and when the circumstances of the system becomes yellow. The great feature of the present invention is that the promotion of chemical strengthening is preferably in the state of Fe 3+ and is preferably melted by oxidizability. However, in general, Fe 2+ and Fe 3+ are coexistent in the glass, so All are in the state of Fe 3+ . Therefore, when the content of Fe 2 O 3 is large, a small amount of Fe 2+ may be present. In this case, in order to exhibit green color, Fe 2 O 3 and the aforementioned green coloring agent may be used. And use it. Further, although the yellow color exhibited by Fe 3+ is light, Fe 2 O 3 may be used in combination with the above-mentioned yellow coloring agent in the same manner.

TiO2係提高玻璃之耐曝晒作用性，且同時為有提高因其他之有色離子所產生之著色效果的成分。若其含量小於0.001%則無法使耐曝晒作用性提升。因此，而使含有0.001%以上。且宜為0.01%以上，較佳則係0.02%以上。又，若其含量超過3%，則會促進玻璃之結晶化傾向而易發生失透明。因此，其含量係令為3%以下。且宜為2.8%以下，較佳則係2.5%以下。 The TiO 2 system enhances the anti-exposure effect of the glass, and at the same time, has a component that enhances the coloring effect by other colored ions. If the content is less than 0.001%, the exposure resistance cannot be improved. Therefore, it is contained in an amount of 0.001% or more. It is preferably 0.01% or more, and preferably 0.02% or more. Moreover, when the content exceeds 3%, the crystallization tendency of the glass is promoted, and the loss of transparency is liable to occur. Therefore, the content is 3% or less. It is preferably 2.8% or less, preferably 2.5% or less.

著色成分之MpOq(但是，M係選自Co、Cu、V、Cr、Pr、Ce、Bi、Eu、Mn、Er、Ni、Nd、W、Rb、Sn及Ag中之至少一種，且p與q係M與O之原子比)係用以將玻璃著色成所需之顏色的成分，藉由適當地選擇著色成分而可獲得例如藍色系、綠色系、黄色系、紫色~粉紅色系及紅色 系等之著色玻璃。 MpOq of the coloring component (however, M is selected from at least one of Co, Cu, V, Cr, Pr, Ce, Bi, Eu, Mn, Er, Ni, Nd, W, Rb, Sn, and Ag, and p is The q atomic ratio of M to O is used to color the glass into a desired color component, and by appropriately selecting the coloring component, for example, a blue color, a green color, a yellow color, a purple color, and a pink color can be obtained. red The colored glass of the system.

具體而言，例如使用選自Co3O4及CuO中之至少一種成分，則可獲得藍色系之著色玻璃。使用選自V2O5、Cr2O3、CuO及Pr6O11中之至少一種成分，則可獲得綠色系之著色玻璃。使用選自CeO2、V2O5、Bi2O3及Eu2O3中之至少一種成分，則可獲得黄色系之著色玻璃。而使用選自MnO2、Er2O3、NiO、Nd2O3及WO3中之至少一種成分，則可獲得紫色~粉紅色系之著色玻璃。 Specifically, for example, a blue-based colored glass can be obtained by using at least one component selected from the group consisting of Co 3 O 4 and CuO. When at least one component selected from the group consisting of V 2 O 5 , Cr 2 O 3 , CuO, and Pr 6 O 11 is used, a green colored glass can be obtained. When at least one component selected from the group consisting of CeO 2 , V 2 O 5 , Bi 2 O 3 and Eu 2 O 3 is used, a yellow colored glass can be obtained. When at least one component selected from the group consisting of MnO 2 , Er 2 O 3 , NiO, Nd 2 O 3 and WO 3 is used, a purple-pink colored glass can be obtained.

又，使用選自Cu2O及Ag2O中之至少一種成分，則可獲得紅色系之著色玻璃。 Further, when at least one component selected from the group consisting of Cu 2 O and Ag 2 O is used, a red colored glass can be obtained.

因若前述MpOq之著色成分的含量小於0.001%則玻璃之著色變得極淡，而若不將玻璃增厚則無法作為有色來辨識，故為使擁有作為著色框體之設計性，而必須將厚度設計得相當厚。因此，而使含有0.001%以上。且宜為0.05%以上，較佳則係0.1%以上。又，若其含量超過10%則玻璃會變得不穩定。因此，其含量係令為10%以下。且宜為8%以下，較佳則係5%以下。 If the content of the color component of the above MpOq is less than 0.001%, the color of the glass becomes extremely light, and if the glass is not thickened, it cannot be recognized as a colored color. Therefore, in order to possess the design as a colored frame, it is necessary to The thickness is designed to be quite thick. Therefore, it is contained in an amount of 0.001% or more. It is preferably 0.05% or more, preferably 0.1% or more. Moreover, if the content exceeds 10%, the glass becomes unstable. Therefore, the content is 10% or less. It is preferably 8% or less, preferably 5% or less.

對於本實施形態之化學強化用玻璃係可依所需而使其含有B2O3、K2O、MgO、ZnO、RO(但是，R係選自Sr、Ba及Ca中之至少一種)及ZrO2。 The glass for chemical strengthening according to the embodiment may contain B 2 O 3 , K 2 O, MgO, ZnO, or RO as required (however, R is at least one selected from the group consisting of Sr, Ba, and Ca) and ZrO 2 .

藉由使含有B2O3可使耐氣候性提升。但是，若其含量小於0.1%則就提升耐氣候性而言有無法獲得有意義的效果之虞。因此，宜使含有0.1%以上。且較佳係0.5%以上，特別理想的則係2%以上。又，若其含量超過12%則會發生 因揮發造成的擦痕，而成品率會降低。因此，其含量係令為12%以下。且宜為10%以下，較佳則係8%以下。 Weather resistance can be improved by containing B 2 O 3 . However, if the content is less than 0.1%, there is a possibility that a satisfactory effect cannot be obtained in terms of improving weather resistance. Therefore, it is preferred to contain 0.1% or more. It is preferably 0.5% or more, and particularly preferably 2% or more. Further, if the content exceeds 12%, scratches due to volatilization occur, and the yield is lowered. Therefore, the content is such that it is 12% or less. It is preferably 10% or less, preferably 8% or less.

藉由使含有K2O不但可使熔融性提升，同時還可增大化學強化中之離子交換速度。但是，若其含量小於0.1%則就提升耐氣候性而言可能無法獲得有意義的效果，或者是就提升離子交換速度而言有無法獲得有意義的效果之虞。因此，而宜使含有0.1%以上。且較佳係0.2%以上，特別理想的則係0.5%以上。又，若其含量超過5%則耐氣候性會降低。因此，其含量係令為5%以下。且宜為4.5%以下，較佳則係4%以下。 By containing K 2 O, not only the meltability can be improved, but also the ion exchange rate in chemical strengthening can be increased. However, if the content is less than 0.1%, it may not be possible to obtain a meaningful effect in terms of improving weather resistance, or it may be impossible to obtain a meaningful effect in terms of increasing the ion exchange rate. Therefore, it is preferable to contain 0.1% or more. It is preferably 0.2% or more, and particularly preferably 0.5% or more. Moreover, if the content exceeds 5%, the weather resistance will be lowered. Therefore, the content is 5% or less. It is preferably 4.5% or less, preferably 4% or less.

藉由使含有MgO則可使熔融性提升。但是，若其含量小於0.1%則就提升熔融性而言有無法獲得有意義的效果之虞。因此，而宜使含有0.1%以上。且較佳係0.2%以上，特別理想的則係0.5%以上。又，若其含量超過15%則耐氣候性會降低。因此，其含量係令為15%以下。且宜為14%以下，較佳則係12%以下。 The meltability can be improved by containing MgO. However, if the content is less than 0.1%, there is a possibility that a meaningful effect cannot be obtained in terms of improving the meltability. Therefore, it is preferable to contain 0.1% or more. It is preferably 0.2% or more, and particularly preferably 0.5% or more. Moreover, if the content exceeds 15%, the weather resistance will be lowered. Therefore, the content is made 15% or less. It is preferably 14% or less, preferably 12% or less.

藉由使含有ZnO則可使耐氣候性提升。但是，若其含量小於0.1%則就提升耐氣候性而言有無法獲得有意義的效果之虞。因此，而宜使含有0.1%以上。且較佳係0.2%以上，特別理想的則係0.3%以上。又，若其含量超過5%則玻璃會變得不穩定。因此，其含量係令為5%以下。且宜為4%以下，較佳則係3%以下。 Weather resistance can be improved by including ZnO. However, if the content is less than 0.1%, there is a possibility that a satisfactory effect cannot be obtained in terms of improving weather resistance. Therefore, it is preferable to contain 0.1% or more. It is preferably 0.2% or more, and particularly preferably 0.3% or more. Moreover, if the content exceeds 5%, the glass becomes unstable. Therefore, the content is 5% or less. It is preferably 4% or less, preferably 3% or less.

藉由使含有RO(但是，R係選自Sr、Ba及Ca中之至少一種)則可使熔融性提升。但就其另一面而言，則因有 使化學強化特性惡化之虞，故添加應止於所需之最小限度，且其含量合計係以1%以下為宜，而以0.5%以下較佳。 The meltability can be improved by including RO (however, R is selected from at least one of Sr, Ba, and Ca). But on the other side, because of Since the chemical strengthening characteristics are deteriorated, the addition should be kept to a minimum required, and the total content thereof is preferably 1% or less, and preferably 0.5% or less.

藉由使含有ZrO2則可增大離子交換速度。但是，若其含量小於0.01%則就提升離子交換速度而言有無法獲得有意義的效果之虞。因此，而宜使含有0.01%以上。且較佳係0.05%以上，特別理想的則係0.1%以上。又，若其含量超過5%則熔融性會降低而有成為未熔融物而殘留於玻璃中之虞。因此，其含量係令為5%以下。且宜為4%以下，較佳則係3%以下。 The ion exchange rate can be increased by containing ZrO 2 . However, if the content is less than 0.01%, there is a possibility that a meaningful effect cannot be obtained in terms of increasing the ion exchange rate. Therefore, it is preferable to contain 0.01% or more. It is preferably 0.05% or more, and particularly preferably 0.1% or more. Moreover, when the content exceeds 5%, the meltability is lowered, and the unmelted material remains in the glass. Therefore, the content is 5% or less. It is preferably 4% or less, preferably 3% or less.

於本實施形態之化學強化玻璃中，更可依所需而使其含有SO3、SnO及Sb2O3。 In the chemically strengthened glass of the present embodiment, SO 3 , SnO, and Sb 2 O 3 may be contained as needed.

SO3係作為澄清劑來發揮作用之成分。但是，若其含量小於0.01%則有無法獲得所期望之澄清作用之虞。因此，使含有SO3的情況時，宜使含有0.01%以上。且較佳係0.03%以上，特別理想的則係0.05%以上。又，若其含量超過1%則反而會成為氣泡之產源，而有玻璃之燒穿變慢、氣泡個數增加之虞。因此，其含量係令為1%以下。且較佳係0.8%以下，特別理想的則係0.6%以下。 SO 3 is a component that functions as a clarifying agent. However, if the content is less than 0.01%, the desired clarification effect cannot be obtained. Therefore, when SO 3 is contained, it is preferable to contain 0.01% or more. It is preferably 0.03% or more, and particularly preferably 0.05% or more. Moreover, if the content exceeds 1%, it will become a source of bubbles, and the burning of the glass will be slow and the number of bubbles will increase. Therefore, the content is preferably 1% or less. It is preferably 0.8% or less, and particularly preferably 0.6% or less.

SnO係於使著色為紅色系的情況時，具有於後處理步驟之熱處理中作為將Cu2O或Ag2O還原，而使析出Cu或Ag膠體之所謂的熱還原劑的作用。但是，若其含量小於0.05%則有無法獲得所期望之作為熱還原劑的作用之虞。因此，使含有SnO時，宜使含有0.05%以上。且較佳係0.1%以上，特別理想的則係0.2%以上。又，若其含量超過3%則玻 璃會變得不穩定而有變得容易失透明之虞。因此，其含量係宜令為3%以下。且較佳係2.8%以下，特別理想的則係2.5%以下。 When the SnO is colored in a red color, it has a function as a so-called thermal reducing agent which reduces Cu 2 O or Ag 2 O and precipitates Cu or Ag colloid in the heat treatment in the post-treatment step. However, if the content is less than 0.05%, the desired effect as a thermal reducing agent cannot be obtained. Therefore, when SnO is contained, it is preferable to contain 0.05% or more. It is preferably 0.1% or more, and particularly preferably 0.2% or more. Moreover, if the content exceeds 3%, the glass becomes unstable and it becomes easy to lose transparency. Therefore, the content should preferably be 3% or less. It is preferably 2.8% or less, and particularly preferably 2.5% or less.

Sb2O3係於使著色為紅色系的情況時，與SnO相同具有作為熱還原劑的作用。但是，若其含量小於0.05%則有無法獲得所期望之作為熱還原劑的作用之虞。因此，使含有Sb2O3時，宜使含有0.05%以上。且較佳係0.1%以上，特別理想的則係0.2%以上。又，若其含量超過5%則玻璃會變得不穩定而有變得容易失透明之虞。因此，其含量係宜令為5%以下。且較佳係3%以下，特別理想的則係1%以下。Sb2O3因係環境危害性物質，故作為熱還原劑係以使用SnO為宜。 When Sb 2 O 3 is colored in a red color, it functions as a thermal reducing agent similarly to SnO. However, if the content is less than 0.05%, the desired effect as a thermal reducing agent cannot be obtained. Therefore, when Sb 2 O 3 is contained, it is preferable to contain 0.05% or more. It is preferably 0.1% or more, and particularly preferably 0.2% or more. Moreover, if the content exceeds 5%, the glass becomes unstable and it becomes easy to lose transparency. Therefore, the content should preferably be 5% or less. It is preferably 3% or less, and particularly preferably 1% or less. Since Sb 2 O 3 is an environmentally hazardous substance, it is preferable to use SnO as a thermal reducing agent.

另外，以上就與本發明之化學強化用玻璃1之第1實施形態的化學強化用玻璃進行了敍述，然而與本發明相關之化學強化用玻璃2之第1實施形態的化學強化用玻璃，除了K2O之含有比率為0~15%的點之外，係與化學強化用玻璃1之第1實施形態的化學強化用玻璃相同。另外，藉由使含有K2O不但可使熔融性提升，同時還可增大化學強化中之離子交換速度。但是，若其含量小於0.1%則就提升熔融性而言可能無法獲得有意義的效果，或者係就提升離子交換速度而言有無法獲得有意義的效果之虞。因此，而宜使含有0.1%以上。且較佳係0.2%以上，特別理想的則係0.5%以上。又，若其含量超過15%，則於玻璃表面已產生有壓痕時會變得容易自壓痕產生裂痕，而玻璃的強度會降低。因此，其含 量係令為15%以下。且宜為12%以下，較佳則係10%以下。 In addition, although the glass for chemical strengthening of the first embodiment of the chemical strengthening glass 1 of the present invention has been described above, the chemical strengthening glass of the first embodiment of the chemical strengthening glass 2 of the present invention is The chemical strengthening glass of the first embodiment of the chemical strengthening glass 1 is the same as the point of the K 2 O content ratio of 0 to 15%. Further, by containing K 2 O, not only the meltability can be improved, but also the ion exchange rate in chemical strengthening can be increased. However, if the content is less than 0.1%, a meaningful effect may not be obtained in terms of improving the meltability, or a meaningful effect may not be obtained in terms of increasing the ion exchange rate. Therefore, it is preferable to contain 0.1% or more. It is preferably 0.2% or more, and particularly preferably 0.5% or more. Further, when the content exceeds 15%, cracks are likely to occur from the indentation when the surface of the glass is indented, and the strength of the glass is lowered. Therefore, the content is made 15% or less. It is preferably 12% or less, preferably 10% or less.

本實施形態之化學強化用玻璃特別是藉由使其含有Fe2O3及TiO2，不但可具備優異之耐曝晒作用性，同時還可藉由施行化學強化處理，而於表面上形成具有充分深度及表面壓縮應力的壓縮應力層，故可製得業經著色之高強度的化學強化玻璃。所製得之化學強化玻璃作為構成電子機器之外裝的玻璃框體的材料係有用的。 In particular, the chemical strengthening glass of the present embodiment contains not only Fe 2 O 3 and TiO 2 but also excellent anti-exposure action, and can be formed on the surface by chemical strengthening treatment. The compressive stress layer of depth and surface compressive stress can produce high strength chemically strengthened glass which is colored.

又，將本實施形態之化學強化用玻璃進行化學強化之方法，只要是可將玻璃表層之Na2O與熔融鹽中之K2O進行離子交換之方法則無特別限定，例如可用使玻璃板或者係玻璃成形品浸漬於已加熱至400~550℃之硝酸鉀(KNO3)熔融鹽中2~20個小時之方法等。 And the chemical form of the reinforcing method of the present embodiment of a chemically strengthened glass, as long as the glass surface of Na 2 O may be a method of ion-exchanged with molten salt of K 2 O is not particularly limited, the glass plate can be used e.g. Alternatively, the glass molded article may be immersed in a molten salt of potassium nitrate (KNO 3 ) heated to 400 to 550 ° C for 2 to 20 hours.

(此處，T1：使400W高壓水銀燈的光以間隔距離15cm照射兩面業經鏡面光學研磨且厚度為2mm之化學強化用玻璃的研磨面50小時後，分光透射率曲線中波長 380nm~780nm的平均透射率；T0：光照射前之分光透射率曲線中，波長380nm~780nm的平均透射率) (Here, T1: The light of the 400W high-pressure mercury lamp is irradiated on the polished surface of the chemical strengthening glass with a mirror surface optical polishing and a thickness of 2 mm at a distance of 15 cm, and the wavelength in the spectral transmittance curve Average transmittance from 380 nm to 780 nm; T0: average transmittance of wavelengths from 380 nm to 780 nm in the spectral transmittance curve before light irradiation)

該透射率劣化度係評估化學強化用玻璃之耐曝晒作用性之指標。 The degree of deterioration of the transmittance is an index for evaluating the resistance to exposure of the glass for chemical strengthening.

(第2實施形態) (Second embodiment)

其次，將就本發明之第2實施形態的化學強化用玻璃予以說明。 Next, a glass for chemical strengthening according to a second embodiment of the present invention will be described.

第2實施形態的化學強化用玻璃係著色為藍色系之玻璃，譬如可獲得以CIE色度座標上之(x,y)值滿足0.00≦x≦0.32及0.00≦y≦0.40之色調的玻璃。 The glass for chemical strengthening according to the second embodiment is colored in a blue-based glass, and for example, a glass having a color tone satisfying the (x, y) value of 0.00≦x≦0.32 and 0.00≦y≦0.40 on the CIE chromaticity coordinate can be obtained. .

有關本發明之化學強化用玻璃1之第2實施形態的化學強化用玻璃係含有SiO2、Al2O3、Na2O、Fe2O3、TiO2，以及作為著色成分之Co3O4及/或CuO(即，選自於由Co3O4及CuO所構成群組中之至少一種)當作為必要成分者。 The glass for chemical strengthening according to the second embodiment of the chemical strengthening glass 1 of the present invention contains SiO 2 , Al 2 O 3 , Na 2 O, Fe 2 O 3 , TiO 2 , and Co 3 O 4 as a coloring component. And/or CuO (i.e., selected from at least one of the group consisting of Co 3 O 4 and CuO) as an essential component.

該第2實施形態之化學強化用玻璃的組成係如下：SiO2：55~80%、Al2O3：3~16%、Na2O：5~16%、0~12%之B2O3、Fe2O3：0.001~3%、TiO2：0.001~3%、Co3O4：0~3%、CuO：0~8%、(Co3O4+CuO)：0.01~8%、B2O3：0~12%、 K2O：0~5%、MgO：0~15%、ZnO：0~5%、ZrO2：0~5%、及RO：0~1%(但是，R係選自Sr、Ba及Ca中之至少一種)。 The composition of the glass for chemical strengthening according to the second embodiment is as follows: SiO 2 : 55 to 80%, Al 2 O 3 : 3 to 16%, Na 2 O: 5 to 16%, and 0 to 12% of B 2 O. 3 , Fe 2 O 3 : 0.001 to 3%, TiO 2 : 0.001 to 3%, Co 3 O 4 : 0 to 3%, CuO: 0 to 8%, (Co 3 O 4 + CuO): 0.01 to 8% , B 2 O 3 : 0 to 12%, K 2 O: 0 to 5%, MgO: 0 to 15%, ZnO: 0 to 5%, ZrO 2 : 0 to 5%, and RO: 0 to 1% ( However, R is selected from at least one of Sr, Ba, and Ca).

為本實施形態之化學強化用玻璃之必要成分的SiO2，係構成玻璃骨架之成分。若其含量小於55%，作為玻璃的穩定性可能會降低，或者是耐氣候性會降低。因此，而使含有55%以上。且宜為58%以上，較佳則係60%以上。又，若其含量超過80%則玻璃的黏性會增大而熔融性會降低。因此，其含量係令為80%以下。且宜為78%以下，較佳則係75%以下。 SiO 2 which is an essential component of the glass for chemical strengthening of the present embodiment constitutes a component of the glass skeleton. If the content is less than 55%, the stability as glass may be lowered, or the weather resistance may be lowered. Therefore, it contains 55% or more. And it is preferably 58% or more, preferably 60% or more. Moreover, if the content exceeds 80%, the viscosity of the glass increases and the meltability decreases. Therefore, the content is 80% or less. It is preferably 78% or less, preferably 75% or less.

Al2O3係使玻璃的耐氣候性提升之成分。若其含量小於3%則耐氣候性會降低。因此，而使含有3%以上。且宜為4%以上，較佳則係5%以上。又，若其含量超過16%，則玻璃的黏性會變高而均質的熔融會變得困難。因此，其含量係令為16%以下。且宜為14%以下，較佳則係12%以下。 Al 2 O 3 is a component that enhances the weather resistance of glass. If the content is less than 3%, the weather resistance will be lowered. Therefore, it contains 3% or more. And it is preferably 4% or more, and preferably 5% or more. Moreover, when the content exceeds 16%, the viscosity of the glass becomes high, and homogeneous melting becomes difficult. Therefore, the content is such that it is 16% or less. It is preferably 14% or less, preferably 12% or less.

Na2O不但係使玻璃的熔融性提升之成分，同時亦係用以藉由離子交換而使形成壓縮應力層於玻璃表面上的必要成分。若其含量小於5%則熔融性會降低，且變得難以藉由離子交換而於玻璃表面上形成所需之壓縮應力層。因此，而使含有5%以上。且宜為6%以上，較佳則係8%以上。又，若其含量超過16%則耐氣候性會降低。因此，其含量係令為16%以下。且宜為15%以下，較佳則係14%以下。 Na 2 O is not only a component that enhances the meltability of the glass, but also an essential component for forming a compressive stress layer on the surface of the glass by ion exchange. If the content is less than 5%, the meltability is lowered, and it becomes difficult to form a desired compressive stress layer on the glass surface by ion exchange. Therefore, it contains 5% or more. It is preferably 6% or more, preferably 8% or more. Moreover, if the content exceeds 16%, the weather resistance will be lowered. Therefore, the content is such that it is 16% or less. It is preferably 15% or less, preferably 14% or less.

Fe2O3係使玻璃中之離子的移動容易而促進離子交換的成分。若其含量小於0.001%則無法獲得促進離子交換效果。因此，而使含有0.001%以上。且宜為0.01%以上，較佳則係0.03%以上。又，若其含量超過3%則玻璃會變得不穩定而容易發生失透明。因此，其含量係令為3%以下。且宜為2.8%以下，較佳則係2.5%以下。 Fe 2 O 3 is a component that facilitates the movement of ions in the glass and promotes ion exchange. If the content is less than 0.001%, the effect of promoting ion exchange cannot be obtained. Therefore, it is contained in an amount of 0.001% or more. It is preferably 0.01% or more, preferably 0.03% or more. Moreover, if the content exceeds 3%, the glass becomes unstable and the loss of transparency tends to occur. Therefore, the content is 3% or less. It is preferably 2.8% or less, preferably 2.5% or less.

再者，藉由添加Fe2O3可促進離子交換，係推測因玻璃中存在著4配位之Fe3+，而使玻璃中之非架橋氧成為架橋氧，結果因負的電荷密度變低，而使Na+離子變得容易活動所致。 Furthermore, ion exchange can be promoted by the addition of Fe 2 O 3 , which is presumed to be due to the presence of 4-coordinated Fe 3+ in the glass, so that the non-bridging oxygen in the glass becomes bridging oxygen, resulting in a low negative charge density. And make Na + ions become easy to move.

TiO2係提高玻璃之耐曝晒作用性，且同時為有提高因其他之有色離子所產生之著色的效果的成分。若其含量小於0.001%則無法使耐曝晒作用性提升。因此，而使含有0.001%以上。且宜為0.01%以上，較佳則係0.02%以上。又，若其含量超過3%，則會促進玻璃之結晶化傾向而容易發生失透明。因此，其含量係令為3%以下。且宜為2.8%以下，較佳則係2.5%以下。 The TiO 2 system enhances the anti-exposure effect of the glass, and at the same time, has a effect of improving the coloring effect by other colored ions. If the content is less than 0.001%, the exposure resistance cannot be improved. Therefore, it is contained in an amount of 0.001% or more. It is preferably 0.01% or more, and preferably 0.02% or more. Moreover, when the content exceeds 3%, the crystallization tendency of the glass is promoted, and the loss of transparency is likely to occur. Therefore, the content is 3% or less. It is preferably 2.8% or less, preferably 2.5% or less.

作為著色成分所含之選自於由Co3O4及CuO所構成群組中之至少一種，係用以將玻璃著色成藍色系之色彩的必要成分。Co3O4或CuO，或者是Co3O4及CuO之合計的含量若小於0.01%則無法獲得所需之藍色的玻璃。因此，而使含有0.01%以上。且宜為0.05%以上，較佳則係0.1%以上。又，若其含量超過8%則玻璃會變得不穩定。因此，含量係令為8%以下。且宜為7%以下，較佳則係6%以下。 The coloring component is at least one selected from the group consisting of Co 3 O 4 and CuO, and is an essential component for coloring the glass into a blue color. When Co 3 O 4 or CuO or a total content of Co 3 O 4 and CuO is less than 0.01%, the desired blue glass cannot be obtained. Therefore, it is contained in an amount of 0.01% or more. It is preferably 0.05% or more, preferably 0.1% or more. Moreover, if the content exceeds 8%, the glass becomes unstable. Therefore, the content is 8% or less. It is preferably 7% or less, preferably 6% or less.

但是，若Co3O4之含量超過3%則著色會變得過濃，而設計性會降低。因此，Co3O4之含量係令為3%以下。且宜為2.8%以下，較佳則係2.5%以下。又，若CuO之含量超過8%則不但著色會變得過濃且同時玻璃亦會變得不穩定。因此，CuO之含量係令為8%以下。且宜為7%以下，較佳則係5%以下。 However, if the content of Co 3 O 4 exceeds 3%, the coloring becomes too thick and the design property is lowered. Therefore, the content of Co 3 O 4 is 3% or less. It is preferably 2.8% or less, preferably 2.5% or less. Moreover, when the content of CuO exceeds 8%, not only the coloring will become too thick, but also the glass will become unstable. Therefore, the content of CuO is 8% or less. It is preferably 7% or less, preferably 5% or less.

另外，於本實施形態中，只要在無損藍色系之著色的範圍內亦可使含有選自前述著色成分以外的著色成分MpOq(但是，在此，M係選自V、Cr、Pr、Ce、Bi、Eu、Mn、Er、Ni、Nd、W、Rb、Sn及Ag中之至少一種，且p與q係M與O之原子比)中之至少一種。而該情況時，宜使與前述著色成分之合計含有率不超過10%。其含量若超過10%則玻璃會變得不穩定。故宜為9%以下，且較佳係8%以下。 Further, in the present embodiment, the coloring component MpOq selected from the coloring components other than the coloring component may be contained within a range in which the blue color is not damaged (however, the M system is selected from the group consisting of V, Cr, Pr, and Ce). At least one of Bi, Eu, Mn, Er, Ni, Nd, W, Rb, Sn, and Ag, and at least one of p and q atomic ratios of M to O. In this case, the total content of the coloring component and the coloring component is preferably not more than 10%. If the content exceeds 10%, the glass becomes unstable. Therefore, it is preferably 9% or less, and preferably 8% or less.

藉由使含有B2O3可使耐氣候性提升。但是，若其含量小於0.1%則就提升耐氣候性而言有無法獲得有意義的效果之虞。因此，宜使含有0.1%以上。且較佳係0.5%以上，特別理想的則係2%以上。又，若其含量超過12%則會發生因揮發造成的擦痕，而成品率會降低。因此，其含量係令為12%以下。且宜為10%以下，較佳則係8%以下。 Weather resistance can be improved by containing B 2 O 3 . However, if the content is less than 0.1%, there is a possibility that a satisfactory effect cannot be obtained in terms of improving weather resistance. Therefore, it is preferred to contain 0.1% or more. It is preferably 0.5% or more, and particularly preferably 2% or more. Further, if the content exceeds 12%, scratches due to volatilization occur, and the yield is lowered. Therefore, the content is such that it is 12% or less. It is preferably 10% or less, preferably 8% or less.

藉由使含有K2O不但可使熔融性提升，同時還可增大化學強化中之離子交換速度。但是，若其含量小於0.1% 則就提升熔融性而言可能無法獲得有意義的效果，或者是就提升離子交換速度而言有無法獲得有意義的效果之虞。因此，而宜使含有0.1%以上。且較佳係0.2%以上，特別理想的則係0.5%以上。又，若其含量超過5%則耐氣候性會降低。因此，其含量係令為5%以下。且宜為4.5%以下，較佳則係4%以下。 By containing K 2 O, not only the meltability can be improved, but also the ion exchange rate in chemical strengthening can be increased. However, if the content is less than 0.1%, a meaningful effect may not be obtained in terms of improving the meltability, or a meaningful effect may not be obtained in terms of increasing the ion exchange rate. Therefore, it is preferable to contain 0.1% or more. It is preferably 0.2% or more, and particularly preferably 0.5% or more. Moreover, if the content exceeds 5%, the weather resistance will be lowered. Therefore, the content is 5% or less. It is preferably 4.5% or less, preferably 4% or less.

藉由使含有MgO可使熔融性提升。但是，若其含量小於0.1%則就提升熔融性而言有無法獲得有意義的效果之虞。因此，而宜使含有0.1%以上。且較佳係0.2%以上，特別理想的則係0.5%以上。又，若其含量超過15%則耐氣候性會降低。因此，其含量係令為15%以下。且宜為14%以下，較佳則係12%以下。 The meltability can be improved by containing MgO. However, if the content is less than 0.1%, there is a possibility that a meaningful effect cannot be obtained in terms of improving the meltability. Therefore, it is preferable to contain 0.1% or more. It is preferably 0.2% or more, and particularly preferably 0.5% or more. Moreover, if the content exceeds 15%, the weather resistance will be lowered. Therefore, the content is made 15% or less. It is preferably 14% or less, preferably 12% or less.

藉由使含有ZnO可使耐氣候性提升。但是，若其含量小於0.1%則就提升耐氣候性而言有無法獲得有意義的效果之虞。因此，而宜使含有0.1%以上。且較佳係0.2%以上，特別理想的則係0.3%以上。又，若其含量超過5%則玻璃會變得不穩定。因此，其含量係令為5%以下。且宜為4%以下，較佳則係3%以下。 Weather resistance is improved by including ZnO. However, if the content is less than 0.1%, there is a possibility that a satisfactory effect cannot be obtained in terms of improving weather resistance. Therefore, it is preferable to contain 0.1% or more. It is preferably 0.2% or more, and particularly preferably 0.3% or more. Moreover, if the content exceeds 5%, the glass becomes unstable. Therefore, the content is 5% or less. It is preferably 4% or less, preferably 3% or less.

藉由使含有RO(但是，R係選自Sr、Ba及Ca中之至少一種)可使熔融性提升。但就其另一面而言，因有使化學強化特性惡化之虞，故其添加係應止於所需之最小限度，且其含量合計則以1%以下為宜，而以0.5%以下較佳。 The meltability can be improved by including RO (however, R is selected from at least one of Sr, Ba, and Ca). On the other hand, since the chemical strengthening characteristics are deteriorated, the addition should be kept to a minimum required, and the total content is preferably 1% or less, and preferably 0.5% or less. .

藉由使含有ZrO2則可增大離子交換速度。但是，若其含量小於0.01%則就提升離子交換速度而言有無法獲 得有意義的效果之虞。因此，而宜使含有0.01%以上。且較佳係0.05%以上，特別理想的則係0.1%以上。又，若其含量超過5%則熔融性會降低而有成為未熔融物而殘留於玻璃中之虞。因此，其含量係令為5%以下。且宜為4%以下，較佳則係3%以下。 The ion exchange rate can be increased by containing ZrO 2 . However, if the content is less than 0.01%, there is a possibility that a meaningful effect cannot be obtained in terms of increasing the ion exchange rate. Therefore, it is preferable to contain 0.01% or more. It is preferably 0.05% or more, and particularly preferably 0.1% or more. Moreover, when the content exceeds 5%, the meltability is lowered, and the unmelted material remains in the glass. Therefore, the content is 5% or less. It is preferably 4% or less, preferably 3% or less.

於本實施形態之化學強化玻璃中，更可依所需而使其含有SO3。 In the chemically strengthened glass of the present embodiment, SO 3 may be contained as needed.

SO3係作為澄清劑來發揮作用之成分。但是，若其含量小於0.01%則有無法獲得所期望之澄清作用之虞。因此，使含有SO3的情況時，宜使含有0.01%以上。且較佳係0.03%以上，特別理想的則係0.05%以上。又，若其含量超過1%則反而會變為氣泡之產源，而有玻璃之燒穿變慢、氣泡個數增加之虞。因此，其含量係宜令為1%以下。且較佳係0.8%以下，特別理想的則係0.6%以下。 SO 3 is a component that functions as a clarifying agent.

另外，以上就本發明之化學強化用玻璃1之第2實施形態的化學強化用玻璃進行了敍述，然而關於本發明之化學強化用玻璃2之第2實施形態的化學強化用玻璃，除了K2O之含有比率為0~15%的點之外，係與化學強化用玻璃1之第2實施形態的化學強化用玻璃相同。另外，藉由使含有K2O不但可使熔融性提升，同時還可增大化學強化中之離子交換速度。但是，若其含量小於0.1%則就提升熔融性而言可能無法獲得有意義的效果，或者是就提升離子交換速度而言有無法獲得有意義的效果之虞。因此，而宜使含有0.1%以上。且較佳係0.2%以上，特別理想的則係0.5%以上。 又，若其含量超過15%，則於玻璃表面已產生有壓痕時會變得容易自壓痕產生裂痕，而玻璃的強度會降低。因此，其含量係令為15%以下。且宜為12%以下，較佳則係10%以下。 In the chemical strengthening glass of the second embodiment of the chemical strengthening glass 1 of the present invention, the chemical strengthening glass of the second embodiment of the chemical strengthening glass 2 of the present invention is not limited to K 2 . The chemical strengthening glass of the second embodiment of the chemical strengthening glass 1 is the same as the point where the content ratio of O is 0 to 15%. Further, by containing K 2 O, not only the meltability can be improved, but also the ion exchange rate in chemical strengthening can be increased. However, if the content is less than 0.1%, a meaningful effect may not be obtained in terms of improving the meltability, or a meaningful effect may not be obtained in terms of increasing the ion exchange rate. Therefore, it is preferable to contain 0.1% or more. It is preferably 0.2% or more, and particularly preferably 0.5% or more. Further, when the content exceeds 15%, cracks are likely to occur from the indentation when the surface of the glass is indented, and the strength of the glass is lowered. Therefore, the content is made 15% or less. It is preferably 12% or less, preferably 10% or less.

本實施形態之化學強化用玻璃特別是藉由使其含有Fe2O3及TiO2，不但可具備優異之耐曝晒作用性，同時還可藉由施行化學強化處理，而於表面上形成具有充分深度及表面壓縮應力的壓縮應力層，故可製得業已著色成藍色系之高強度的化學強化玻璃。 In particular, the chemical strengthening glass of the present embodiment contains not only Fe 2 O 3 and TiO 2 but also excellent anti-exposure action, and can be formed on the surface by chemical strengthening treatment. A compressive stress layer having a depth and a surface compressive stress can produce a high-strength chemically strengthened glass which has been colored in a blue color.

再者，本實施形態之化學強化用玻璃的製造方法係無特別限定，譬如，適量調配各種的原料，於加熱至約1500~1600℃且熔融之後，藉由消泡及攪拌等使其均質化，並利用周知之下拉法、壓製法等來成形為板狀，或者係進行澆鑄而成形為磚塊狀，並且於緩冷卻後切割為所需之尺寸、且依所需施以研磨加工而製造。 In addition, the method for producing the glass for chemical strengthening of the present embodiment is not particularly limited.

(第3實施形態) (Third embodiment)

接著，將就本發明之第3實施形態的化學強化用玻璃予以說明。 Next, a glass for chemical strengthening according to a third embodiment of the present invention will be described.

第3實施形態的化學強化用玻璃係著色為綠色系的玻璃，譬如可獲得以在CIE色度座標上之(x,y)值滿足0.00≦x≦0.42及0.31≦y≦0.78之色調的玻璃。 The glass for chemical strengthening according to the third embodiment is colored in a green glass, and, for example, a glass having a color tone (x, y) of 0.00≦x≦0.42 and 0.31≦y≦0.78 at a CIE chromaticity coordinate can be obtained. .

本發明之化學強化用玻璃1之第3實施形態的化學強化用玻璃係含有SiO2、Al2O3、Na2O、Fe2O3、TiO2，以及作為著色成分之選自V2O5、Cr2O3、CuO及Pr6O11中之至少一種當作為必要成分者。 The glass for chemical strengthening according to the third embodiment of the chemical strengthening glass 1 of the present invention contains SiO 2 , Al 2 O 3 , Na 2 O, Fe 2 O 3 , TiO 2 , and a coloring component selected from V 2 O. 5. At least one of Cr 2 O 3 , CuO, and Pr 6 O 11 is used as an essential component.

該第3實施形態之化學強化用玻璃的組成係如下：SiO2：55~80%、Al2O3：3~16%、Na2O：5~16%、0~12%之B2O3、Fe2O3：0.001~3%、TiO2：0.001~3%、V2O5：0~5%、Cr2O3：0~5%、CuO：0~8%、Pr6O11：0~3%、 (V2O5+Cr2O3+CuO+Pr6O11)：0.01~8%、B2O3：0~12%、K2O：0~5%、MgO：0~15%、ZnO：0~5%、ZrO2：0~5%、及RO：0~1%(但是，R係選自Sr、Ba及Ca中之至少一種)。 The composition of the chemical strengthening glass according to the third embodiment is as follows: SiO 2 : 55 to 80%, Al 2 O 3 : 3 to 16%, Na 2 O: 5 to 16%, and 0 to 12% of B 2 O. 3 , Fe 2 O 3 : 0.001 to 3%, TiO 2 : 0.001 to 3%, V 2 O 5 : 0 to 5%, Cr 2 O 3 : 0 to 5%, CuO: 0 to 8%, Pr 6 O 11 : 0 to 3%, (V 2 O 5 + Cr 2 O 3 + CuO + Pr 6 O 11 ): 0.01 to 8%, B 2 O 3 : 0 to 12%, K 2 O: 0 to 5%, MgO: 0 to 15%, ZnO: 0 to 5%, ZrO 2 : 0 to 5%, and RO: 0 to 1% (however, R is at least one selected from the group consisting of Sr, Ba, and Ca).

為本實施形態之化學強化用玻璃之必要成分的SiO2，係構成玻璃骨架之成分。若其含量小於55%，作為玻璃的穩定性可能會降低，或者是耐氣候性會降低。因此而使含有55%以上。且宜為58%以上，較佳則係60%以上。又，若其含量超過80%則玻璃的黏性會增大而熔融性會降低。因此，其含量係令為80%以下。且宜為78%以下，較佳則係75%以下。 SiO 2 which is an essential component of the glass for chemical strengthening of the present embodiment constitutes a component of the glass skeleton. If the content is less than 55%, the stability as glass may be lowered, or the weather resistance may be lowered. Therefore, it contains 55% or more. And it is preferably 58% or more, preferably 60% or more. Moreover, if the content exceeds 80%, the viscosity of the glass increases and the meltability decreases. Therefore, the content is 80% or less. It is preferably 78% or less, preferably 75% or less.

Al2O3係使玻璃的耐氣候性提升之成分。若其含量小於3%則耐氣候性會降低。因此，而使含有3%以上。且宜為4%以上，較佳則係5%以上。又，若其含量超過16%，則玻璃的黏性會變高而均質的熔融會變得困難。因此，其含量係令為16%以下。且宜為14%以下，較佳則係12%以下。 Al 2 O 3 is a component that enhances the weather resistance of glass. If the content is less than 3%, the weather resistance will be lowered. Therefore, it contains 3% or more. And it is preferably 4% or more, and preferably 5% or more. Moreover, when the content exceeds 16%, the viscosity of the glass becomes high, and homogeneous melting becomes difficult. Therefore, the content is such that it is 16% or less. It is preferably 14% or less, preferably 12% or less.

Na2O不但係使玻璃的熔融性提升之成分，同時亦係用以藉由離子交換而使形成壓縮應力層於玻璃表面上的必要成分。若其含量小於5%則熔融性會降低，且變得難以藉由離子交換而於玻璃表面上形成所需之壓縮應力層。因此，而使含有5%以上。且宜為6%以上，較佳則係8%以 上。又，若其含量超過16%則耐氣候性會降低。因此，其含量係令為16%以下。且宜為15%以下，較佳則係14%以下。 Na 2 O is not only a component that enhances the meltability of the glass, but also an essential component for forming a compressive stress layer on the surface of the glass by ion exchange. If the content is less than 5%, the meltability is lowered, and it becomes difficult to form a desired compressive stress layer on the glass surface by ion exchange. Therefore, it contains 5% or more. It is preferably 6% or more, preferably 8% or more. Moreover, if the content exceeds 16%, the weather resistance will be lowered. Therefore, the content is such that it is 16% or less. It is preferably 15% or less, preferably 14% or less.

Fe2O3係使玻璃中之離子的移動容易而促進離子交換的成分。若其含量小於0.001%則無法獲得促進離子交換效果。因此，而使含有0.001%以上。且宜為0.01%以上，較佳則係0.03%以上。又，若其含量超過3%則玻璃會變得不穩定而容易發生失透明。因此，其含量係令為3%以下。且宜為2.8%以下，較佳則係2.5%以下。 Fe 2 O 3 is a component that facilitates the movement of ions in the glass and promotes ion exchange. If the content is less than 0.001%, the effect of promoting ion exchange cannot be obtained. Therefore, it is contained in an amount of 0.001% or more. It is preferably 0.01% or more, preferably 0.03% or more. Moreover, if the content exceeds 3%, the glass becomes unstable and the loss of transparency tends to occur. Therefore, the content is 3% or less. It is preferably 2.8% or less, preferably 2.5% or less.

再者，藉由添加Fe2O3可促進離子交換，係推測因玻璃中存在著4配位之Fe3+，而使玻璃中之非架橋氧成為架橋氧，結果因負的電荷密度變低，而使Na+離子變得容易活動所致。 Furthermore, ion exchange can be promoted by the addition of Fe 2 O 3 , which is presumed to be due to the presence of 4-coordinated Fe 3+ in the glass, so that the non-bridging oxygen in the glass becomes bridging oxygen, resulting in a low negative charge density. And make Na + ions become easy to move.

Fe2O3係依據Fe離子之價態來賦予玻璃黄色或者係綠色的色彩。於Fe2+的情況時係綠色~藍綠色，而於Fe3+的情況時則係成為黄色。本發明之大特徵，即對於化學強化的促進係以Fe3+之狀態為宜，且以可氧化性來熔融為理想，但因通常在玻璃中Fe2+與Fe3+係共存的，故無法全部皆為Fe3+之狀態。因此，於Fe2O3之含量多時會有出現少量存在之Fe2+的顏色的情況，此時，為了顯示出呈現綠色，亦可將Fe2O3與前述之綠色的著色劑併用。 Fe 2 O 3 imparts a yellowish or greenish color depending on the valence state of the Fe ions. Fe-based green to blue-green when the case ~ 2+, Fe 3+ and when the circumstances of the system becomes yellow. The great feature of the present invention is that the promotion of chemical strengthening is preferably in the state of Fe 3+ and is preferably melted by oxidizability, but since Fe 2+ and Fe 3+ are usually coexisted in the glass, Not all of them are in the state of Fe 3+ . Therefore, when the content of Fe 2 O 3 is large , a small amount of Fe 2+ may be present. In this case, in order to exhibit green color, Fe 2 O 3 may be used in combination with the green coloring agent described above.

TiO2係提高玻璃之耐曝晒作用性，且同時為有提高因其他之有色離子而產生之著色的效果之成分。若其含量小於0.001%則無法使耐曝晒作用性提升。因此，而使含有0.001%以上。且宜為0.01%以上，較佳則係0.02%以上。 又，若其含量超過3%，則會促進玻璃之結晶化傾向而容易發生失透明。因此，其含量係令為3%以下。且宜為2.8%以下，較佳則係2.5%以下。 TiO 2 improves the anti-exposure effect of glass and at the same time has the effect of improving the coloration caused by other colored ions. If the content is less than 0.001%, the exposure resistance cannot be improved. Therefore, it is contained in an amount of 0.001% or more. It is preferably 0.01% or more, and preferably 0.02% or more. Moreover, when the content exceeds 3%, the crystallization tendency of the glass is promoted, and the loss of transparency is likely to occur. Therefore, the content is 3% or less. It is preferably 2.8% or less, preferably 2.5% or less.

作為著色成分所含之選自V2O5、Cr2O3、CuO及Pr6O11中之至少一種，係用以將玻璃著色成綠色系之色彩的必要成分。該著色成分之含量若小於0.01%則無法獲得所期望之綠色的玻璃。因此，而使含有0.01%以上。且宜為0.05%以上，較佳則係0.1%以上。又，若其含量超過8%則玻璃的著色會變得過濃而變得難辨識色彩之差異。因此，含量係令為8%以下。且宜為7%以下，較佳則係5%以下。 At least one selected from the group consisting of V 2 O 5 , Cr 2 O 3 , CuO, and Pr 6 O 11 contained in the coloring component is an essential component for coloring the glass into a green color. When the content of the coloring component is less than 0.01%, the desired green glass cannot be obtained. Therefore, it is contained in an amount of 0.01% or more. It is preferably 0.05% or more, preferably 0.1% or more. Moreover, if the content exceeds 8%, the color of the glass becomes too thick and it becomes difficult to recognize the difference in color. Therefore, the content is 8% or less. It is preferably 7% or less, preferably 5% or less.

但是，若V2O5之含量超過5%則顏色會變得過濃。因此，V2O5之含量係令為5%以下。且宜為4%以下，較佳則係3%以下。再者，因V離子在3價的狀態下呈現綠色，故以還原性來熔融為理想。若Cr2O3之含量超過5%則顏色會變得過濃。因此，Cr2O3之含量係令為5%以下。且宜為4%以下，較佳則係3%以下。CuO之含量若超過8%則玻璃會變得不穩定。因此，CuO之含量係令為8%以下。且宜為7%以下，較佳則係5%以下。若Pr6O11之含量超過3%則因其為高價之材料，故原料費會變高。因此，Pr6O11之含量係令為3%以下。且宜為2.8%以下，較佳則係2.5%以下。 However, if the content of V 2 O 5 exceeds 5%, the color becomes too thick. Therefore, the content of V 2 O 5 is 5% or less. It is preferably 4% or less, preferably 3% or less. Further, since V ions exhibit green color in a trivalent state, it is desirable to melt them with reductive properties. If the content of Cr 2 O 3 exceeds 5%, the color becomes too thick. Therefore, the content of Cr 2 O 3 is 5% or less. It is preferably 4% or less, preferably 3% or less. If the content of CuO exceeds 8%, the glass becomes unstable. Therefore, the content of CuO is 8% or less. It is preferably 7% or less, preferably 5% or less. If the content of Pr 6 O 11 exceeds 3%, since it is a high-priced material, the raw material cost becomes high. Therefore, the content of Pr 6 O 11 is 3% or less. It is preferably 2.8% or less, preferably 2.5% or less.

另外，於本實施形態中，只要在無損綠色系之著色的範圍內，亦可使含有選自前述著色成分以外的著色成分MpOq(但是，在此，M係選自Co、Ce、Bi、Eu、Mn、Er、Ni、Nd、W、Rb、Sn及Ag中之至少一種，且p與q係M與O 之原子比)中之至少一種。而該情況時，宜使與前述著色成分之合計含有率不超過10%。若含量超過10%則玻璃會變得不穩定。故宜為9%以下，且較佳係8%以下。 Further, in the present embodiment, the coloring component MpOq selected from the coloring components other than the coloring component may be contained within a range in which the coloring of the green color is not impaired (however, the M system is selected from the group consisting of Co, Ce, Bi, and Eu). At least one of Mn, Er, Ni, Nd, W, Rb, Sn, and Ag, and p and q are M and O At least one of atomic ratios). In this case, the total content of the coloring component and the coloring component is preferably not more than 10%. If the content exceeds 10%, the glass becomes unstable. Therefore, it is preferably 9% or less, and preferably 8% or less.

於本實施形態之化學強化用玻璃係可依所需而使其含有B2O3、K2O、MgO、ZnO、RO(但是，R係選自Sr、Ba及Ca中之至少一種)及ZrO2。 The glass for chemical strengthening according to the embodiment may contain B 2 O 3 , K 2 O, MgO, ZnO, and RO as required (however, R is at least one selected from the group consisting of Sr, Ba, and Ca) and ZrO 2 .

藉由使含有B2O3可使耐氣候性提升。但是，若其含量小於0.1%則就提升耐氣候性而言有無法獲得有意義的效果之虞。因此，宜使含有0.1%以上。且較佳係0.5%以上，特別理想的則係2%以上。又，若其含量超過12%則會發生因揮發造成的擦痕，而成品率會降低。因此，其含量係令為12%以下。且宜為10%以下，較佳則係8%以下。 Weather resistance can be improved by containing B 2 O 3 . However, if the content is less than 0.1%, there is a possibility that a satisfactory effect cannot be obtained in terms of improving weather resistance. Therefore, it is preferred to contain 0.1% or more. It is preferably 0.5% or more, and particularly preferably 2% or more. Further, if the content exceeds 12%, scratches due to volatilization occur, and the yield is lowered. Therefore, the content is such that it is 12% or less. It is preferably 10% or less, preferably 8% or less.

藉由使含有K2O不但可使熔融性提升，同時還可增大化學強化中之離子交換速度。但是，若其含量小於0.1%則就提升熔融性而言可能無法獲得有意義的效果，或者是就提升離子交換速度而言有無法獲得有意義的效果之虞。因此，而宜使含有0.1%以上。且較佳係0.2%以上，特別理想的則係0.5%以上。又，若其含量超過5%則耐氣候性會降低。因此，其含量係令為5%以下。且宜為4.5%以下，較佳則係4%以下。 By containing K 2 O, not only the meltability can be improved, but also the ion exchange rate in chemical strengthening can be increased. However, if the content is less than 0.1%, a meaningful effect may not be obtained in terms of improving the meltability, or a meaningful effect may not be obtained in terms of increasing the ion exchange rate. Therefore, it is preferable to contain 0.1% or more. It is preferably 0.2% or more, and particularly preferably 0.5% or more. Moreover, if the content exceeds 5%, the weather resistance will be lowered. Therefore, the content is 5% or less. It is preferably 4.5% or less, preferably 4% or less.

藉由使含有MgO可使熔融性提升。但是，若其含量小於0.1%則就提升熔融性而言有無法獲得有意義的效果之虞。因此，而宜使含有0.1%以上。且較佳係0.2%以上，特別理想的則係0.5%以上。又，若其含量超過15%則耐氣 候性會降低。因此，其含量係令為15%以下。且宜為14%以下，較佳則係12%以下。 The meltability can be improved by containing MgO. However, if the content is less than 0.1%, there is a possibility that a meaningful effect cannot be obtained in terms of improving the meltability. Therefore, it is preferable to contain 0.1% or more. It is preferably 0.2% or more, and particularly preferably 0.5% or more. Also, if the content exceeds 15%, it is resistant to gas. The weather will be reduced. Therefore, the content is made 15% or less. It is preferably 14% or less, preferably 12% or less.

藉由使含有ZnO可使耐氣候性提升。但是，若其含量小於0.1%則就提升耐氣候性而言有無法獲得有意義的效果之虞。因此，而宜使含有0.1%以上。且較佳係0.2%以上，特別理想的則係0.3%以上。又，若其含量超過5%則玻璃會變得不穩定。因此，其含量係令為5%以下。且宜為4%以下，較佳則係3%以下。 Weather resistance is improved by including ZnO. However, if the content is less than 0.1%, there is a possibility that a satisfactory effect cannot be obtained in terms of improving weather resistance. Therefore, it is preferable to contain 0.1% or more. It is preferably 0.2% or more, and particularly preferably 0.3% or more. Moreover, if the content exceeds 5%, the glass becomes unstable. Therefore, the content is 5% or less. It is preferably 4% or less, preferably 3% or less.

藉由使含有RO(但是，R係選自Sr、Ba及Ca中之至少一種)可使熔融性提升。但就其另一面而言，因有使化學強化特性惡化之虞，故其添加應止於所需之最小限度，且其含量合計係以1%以下為宜，而以0.5%以下較佳。 The meltability can be improved by including RO (however, R is selected from at least one of Sr, Ba, and Ca). On the other hand, since the chemical strengthening property is deteriorated, the addition thereof should be kept to a minimum required, and the total content thereof is preferably 1% or less, and preferably 0.5% or less.

藉由使含有ZrO2可增大離子交換速度。但是，若其含量小於0.01%則就提升離子交換速度而言有無法獲得有意義的效果之虞。因此，而宜使含有0.01%以上。且較佳係0.05%以上，特別理想的則係0.1%以上。又，若其含量超過5%則熔融性會降低而有成為未熔融物而殘留於玻璃中之虞。因此，其含量係令為5%以下。且宜為4%以下，較佳則係3%以下。 The ion exchange rate can be increased by including ZrO 2 . However, if the content is less than 0.01%, there is a possibility that a meaningful effect cannot be obtained in terms of increasing the ion exchange rate. Therefore, it is preferable to contain 0.01% or more. It is preferably 0.05% or more, and particularly preferably 0.1% or more. Moreover, when the content exceeds 5%, the meltability is lowered, and the unmelted material remains in the glass. Therefore, the content is 5% or less. It is preferably 4% or less, preferably 3% or less.

於本實施形態之化學強化玻璃中，更可依所需而使其含有SO3。 In the chemically strengthened glass of the present embodiment, SO 3 may be contained as needed.

SO3係作為澄清劑來發揮作用之成分。但是，若其含量小於0.01%則有無法獲得所期望之澄清作用之虞。因此，使含有SO3的情況時，宜使含有0.01%以上。且較佳係 0.03%以上，特別理想的則係0.05%以上。又，若其含量超過1%則反而會變為氣泡之產源，而有玻璃之燒穿變慢、氣泡個數增加之虞。因此，其含量係令為1%以下。且較佳係0.8%以下，特別理想的則係0.6%以下。 SO 3 is a component that functions as a clarifying agent. However, if the content is less than 0.01%, the desired clarification effect cannot be obtained. Therefore, when SO 3 is contained, it is preferable to contain 0.01% or more. It is preferably 0.03% or more, and particularly preferably 0.05% or more. Moreover, if the content exceeds 1%, it will become a source of bubbles, and the burning of the glass will be slow and the number of bubbles will increase. Therefore, the content is preferably 1% or less. It is preferably 0.8% or less, and particularly preferably 0.6% or less.

本實施形態之化學強化用玻璃特別是藉由使其含有Fe2O3及TiO2，不但可具備優異之耐曝晒作用性，同時還可藉由施行化學強化處理，而於表面上形成具有充分深度及表面壓縮應力之壓縮應力層，故可製得業經著色成綠色系之高強度的化學強化玻璃。 In particular, the chemical strengthening glass of the present embodiment contains not only Fe 2 O 3 and TiO 2 but also excellent anti-exposure action, and can be formed on the surface by chemical strengthening treatment. A compressive stress layer having a depth and a surface compressive stress can produce a high-strength chemically strengthened glass which is colored in a green color.

另外，以上就本發明之化學強化用玻璃1之第3實施形態的化學強化用玻璃進行了敍述，然而關於本發明之化學強化用玻璃2之第3實施形態的化學強化用玻璃，除了K2O之含有比率為0~15%的點之外，係與化學強化用玻璃1之第3實施形態的化學強化用玻璃相同。另外，藉由使含有K2O不但可使熔融性提升，同時還可增大化學強化中之離子交換速度。但是，若其含量小於0.1%則就提升熔融性而言可能無法獲得有意義的效果，或者係就提升離子交換速度而言有無法獲得有意義的效果之虞。因此，而宜使含有0.1%以上。且較佳係0.2%以上，特別理想的則係0.5%以上。又，若其含量超過15%，則於玻璃表面已產生有壓痕時會變得容易自壓痕產生裂痕，而玻璃的強度會降低。因此，其含量係令為15%以下。且宜為12%以下，較佳則係10%以下。 In addition, although the glass for chemical strengthening of the third embodiment of the glass for chemical strengthening 1 of the present invention is described above, the glass for chemical strengthening according to the third embodiment of the glass for chemical strengthening 2 of the present invention is not limited to K 2 . The chemical strengthening glass of the third embodiment of the chemical strengthening glass 1 is the same as the point that the content ratio of O is 0 to 15%. Further, by containing K 2 O, not only the meltability can be improved, but also the ion exchange rate in chemical strengthening can be increased. However, if the content is less than 0.1%, a meaningful effect may not be obtained in terms of improving the meltability, or a meaningful effect may not be obtained in terms of increasing the ion exchange rate. Therefore, it is preferable to contain 0.1% or more. It is preferably 0.2% or more, and particularly preferably 0.5% or more. Further, when the content exceeds 15%, cracks are likely to occur from the indentation when the surface of the glass is indented, and the strength of the glass is lowered. Therefore, the content is made 15% or less. It is preferably 12% or less, preferably 10% or less.

再者，本實施形態之化學強化用玻璃的製造方法係無特別限定，譬如，適量調配各種的原料，於加熱至約 1500~1600℃且熔融之後，藉由消泡及攪拌等使其均質化，並利用周知之下拉法、壓製法等來成形為板狀，或者係進行澆鑄而成形為磚塊狀，並且於緩冷卻後切割為所需之尺寸、且依所需施以研磨加工而製造。 Further, the method for producing the glass for chemical strengthening according to the present embodiment is not particularly limited. For example, various materials are blended in an appropriate amount and heated to about After melting at 1500 to 1600 ° C, it is homogenized by defoaming, stirring, etc., and is formed into a plate shape by a known pulling method, a pressing method, or the like, or cast into a brick shape, and is slowed down. After cooling, it is cut to a desired size, and is manufactured by grinding as needed.

又，將本實施形態之化學強化用玻璃進行化學強化之方法，只要是可將玻璃表層之Na2O與熔融鹽中之K2O進行離子交換之方法則無特別之限定，例如可用將玻璃板或者係玻璃成形品浸漬於已加熱至400~550℃之硝酸鉀(KNO3)熔融鹽中2~20個小時之方法等。 Furthermore, the chemical strengthening aspect of this embodiment of the method of chemically strengthening a glass, the glass surface as long as the Na 2 O may be a method of ion-exchanged with molten salt of the K 2 O is not particularly limited, and glass can be used e.g. The plate or the glass molded article is immersed in a molten salt of potassium nitrate (KNO 3 ) which has been heated to 400 to 550 ° C for 2 to 20 hours.

本實施形態之化學強化用玻璃，其以下式求得之透射率劣化度△T係宜為5%以下。較佳則係4%以下。 In the glass for chemical strengthening of the present embodiment, the degree of deterioration of the transmittance ΔT obtained by the following formula is preferably 5% or less. Preferably, it is 4% or less.

△T(%)=[(T0-T1)/T0]×100 △T(%)=[(T0-T1)/T0]×100

接著，將就本發明之第4實施形態的化學強化用玻璃予以說明。 Next, a glass for chemical strengthening according to a fourth embodiment of the present invention will be described.

第4實施形態的化學強化用玻璃係著色為黄色系的玻璃，譬如可獲得以在CIE色度座標上之(x,y)值滿足0.31≦x≦0.66且0.31≦y≦0.58之色調的玻璃。 The glass for chemical strengthening according to the fourth embodiment is colored in a yellow glass, and for example, a glass having a color tone of 0.31≦x≦0.66 and 0.31≦y≦0.58 at a CIE chromaticity coordinate can be obtained. .

本發明之化學強化用玻璃1之第4實施形態的化 學強化用玻璃係含有SiO2、Al2O3、Na2O、Fe2O3、TiO2，以及作為著色成分之選自CeO2、V2O5、Bi2O3及Eu2O3中之至少一種作為必要成分者。 The glass for chemical strengthening according to the fourth embodiment of the chemical strengthening glass 1 of the present invention contains SiO 2 , Al 2 O 3 , Na 2 O, Fe 2 O 3 , TiO 2 , and a coloring component selected from CeO 2 , At least one of V 2 O 5 , Bi 2 O 3 and Eu 2 O 3 is an essential component.

該第4實施形態之化學強化用玻璃的組成係如下：SiO2：55~80%、Al2O3：3~16%、Na2O：5~16%、0~12%之B2O3、Fe2O3：0.001~3%、TiO2：0.001~3%、CeO2：0~3%、V2O5：0~5%、Bi2O3：0~10%、Eu2O3：0~3%、(CeO2+V2O5+Bi2O3+Eu2O3)：0.01~10%、B2O3：0~12%、K2O：0~5%、MgO：0~15%、ZnO：0~5%、ZrO2：0~5%、及RO：0~1%(但是，R係選自Sr、Ba及Ca中之至少一種)。 The composition of the chemical strengthening glass according to the fourth embodiment is as follows: SiO 2 : 55 to 80%, Al 2 O 3 : 3 to 16%, Na 2 O: 5 to 16%, and 0 to 12% of B 2 O. 3 , Fe 2 O 3 : 0.001 to 3%, TiO 2 : 0.001 to 3%, CeO 2 : 0 to 3%, V 2 O 5 : 0 to 5%, Bi 2 O 3 : 0 to 10%, Eu 2 O 3 : 0 to 3%, (CeO 2 + V 2 O 5 + Bi 2 O 3 + Eu 2 O 3 ): 0.01 to 10%, B 2 O 3 : 0 to 12%, K 2 O: 0 to 5 %, MgO: 0 to 15%, ZnO: 0 to 5%, ZrO 2 : 0 to 5%, and RO: 0 to 1% (however, R is at least one selected from the group consisting of Sr, Ba, and Ca).

為本實施形態之化學強化用玻璃之必要成分的SiO2，係構成玻璃骨架之成分。若其含量小於55%，作為玻璃的穩定性可能會降低，或者是耐氣候性會降低。因此，而使含有55%以上。且宜為58%以上，而較佳係60%以上。 又，若其含量超過80%則玻璃的黏性會增大而熔融性會降低。因此，其含量係令為80%以下。且宜為78%以下，較佳則係75%以下。 SiO 2 which is an essential component of the glass for chemical strengthening of the present embodiment constitutes a component of the glass skeleton. If the content is less than 55%, the stability as glass may be lowered, or the weather resistance may be lowered. Therefore, it contains 55% or more. And it is preferably 58% or more, and more preferably 60% or more. Moreover, if the content exceeds 80%, the viscosity of the glass increases and the meltability decreases. Therefore, the content is 80% or less. It is preferably 78% or less, preferably 75% or less.

Al2O3係使玻璃的耐氣候性提升之成分。若其含量小於3%則耐氣候性會降低。因此，而使含有3%以上。且宜為4%以上，而較佳係5%以上。又，若其含量超過16%，則玻璃的黏性會變高而均質的熔融會變得困難。因此，其含量係令為16%以下。且宜為14%以下，較佳則係12%以下。 Al 2 O 3 is a component that enhances the weather resistance of glass. If the content is less than 3%, the weather resistance will be lowered. Therefore, it contains 3% or more. And it is preferably 4% or more, and more preferably 5% or more. Moreover, when the content exceeds 16%, the viscosity of the glass becomes high, and homogeneous melting becomes difficult. Therefore, the content is such that it is 16% or less. It is preferably 14% or less, preferably 12% or less.

Na2O不但係使玻璃的熔融性提升之成分，同時亦係用以藉由離子交換而使形成壓縮應力層於玻璃表面上的必要成分。若其含量小於5%則熔融性會降低，而且會變得難以藉由離子交換而於玻璃表面上形成所需之壓縮應力層。因此，而使含有5%以上。且宜為6%以上，較佳則係8%以上。又，若其含量超過16%則耐氣候性會降低。因此，其含量係令為16%以下。且宜為15%以下，較佳則係14%以下。 Na 2 O is not only a component that enhances the meltability of the glass, but also an essential component for forming a compressive stress layer on the surface of the glass by ion exchange. If the content is less than 5%, the meltability is lowered, and it becomes difficult to form a desired compressive stress layer on the surface of the glass by ion exchange. Therefore, it contains 5% or more. It is preferably 6% or more, preferably 8% or more. Moreover, if the content exceeds 16%, the weather resistance will be lowered. Therefore, the content is such that it is 16% or less. It is preferably 15% or less, preferably 14% or less.

Fe2O3係使玻璃中之離子的移動容易而促進離子交換的成分。若其含量小於0.001%則無法獲得促進離子交換效果。因此，而使含有0.001%以上。而宜為0.01%以上，較佳則係0.03%以上。又，若其含量超過3%則玻璃會變得不穩定而容易發生失透明。因此，其含量係令為3%以下。且宜為2.8%以下，較佳則係2.5%以下。 Fe 2 O 3 is a component that facilitates the movement of ions in the glass and promotes ion exchange. If the content is less than 0.001%, the effect of promoting ion exchange cannot be obtained. Therefore, it is contained in an amount of 0.001% or more. Preferably, it is 0.01% or more, preferably 0.03% or more. Moreover, if the content exceeds 3%, the glass becomes unstable and the loss of transparency tends to occur. Therefore, the content is 3% or less. It is preferably 2.8% or less, preferably 2.5% or less.

再者，藉由添加Fe2O3可促進離子交換，係推測因玻璃中存在著4配位之Fe3+，而使玻璃中之非架橋氧成為架橋氧，結果因負的電荷密度變低，而使Na+離子變得容易 活動所致。 Furthermore, ion exchange can be promoted by the addition of Fe 2 O 3 , which is presumed to be due to the presence of 4-coordinated Fe 3+ in the glass, so that the non-bridging oxygen in the glass becomes bridging oxygen, resulting in a low negative charge density. And make Na + ions become easy to move.

Fe2O3係依據Fe離子之價態來賦予玻璃黄色或者係綠色之色彩。於Fe2+的情況時係綠~藍綠色，而於Fe3+的情況時則係成為黄色。本發明之大特徵，即對於化學強化的促進係以Fe3+之狀態為宜，且以可氧化性來熔融為理想，但因通常在玻璃中Fe2+與Fe3+係共存的，故無法全部皆為Fe3+之狀態。由於Fe3+而呈現的黄色雖淡，但亦可將Fe2O3與前述之黄色的著色劑併用。 Fe 2 O 3 imparts a yellowish or greenish color depending on the valence state of the Fe ions. From green to green-based blue when in the case of Fe 2+, Fe 3+ and when the circumstances of the system becomes yellow. The great feature of the present invention is that the promotion of chemical strengthening is preferably in the state of Fe 3+ and is preferably melted by oxidizability, but since Fe 2+ and Fe 3+ are usually coexisted in the glass, Not all of them are in the state of Fe 3+ . Although the yellow color exhibited by Fe 3+ is light, Fe 2 O 3 may be used in combination with the aforementioned yellow coloring agent.

TiO2係提高玻璃之耐曝晒作用性，且同時為有提高因其他之有色離子而產生之著色的效果之成分。若其含量小於0.001%則無法使耐曝晒作用性提升。因此，而使含有0.001%以上。且宜為0.01%以上，較佳則係0.02%以上。又，若其含量超過3%，則會促進玻璃之結晶化傾向而容發生失透明。因此，其含量係令為3%以下。且宜為2.8%以下，較佳則係2.5%以下。 TiO 2 improves the anti-exposure effect of glass and at the same time has the effect of improving the coloration caused by other colored ions. If the content is less than 0.001%, the exposure resistance cannot be improved. Therefore, it is contained in an amount of 0.001% or more. It is preferably 0.01% or more, and preferably 0.02% or more. Moreover, when the content exceeds 3%, the crystallization tendency of the glass is promoted and the loss of transparency is caused. Therefore, the content is 3% or less. It is preferably 2.8% or less, preferably 2.5% or less.

作為著色成分所含之選自CeO2、V2O5、Bi2O3及Eu2O3中之至少一種，係用以將玻璃著色成黄色系之色彩的必要成分。若該著色成分之含量小於0.01%則無法獲得所要的黄色玻璃。因此，而使含有0.01%以上。且宜為0.05%以上，較佳則係0.1%以上。又，若其含量超過10%則玻璃會變得不穩定。因此，含量係令為10%以下。且宜為8%以下，較佳則係6%以下。 At least one selected from the group consisting of CeO 2 , V 2 O 5 , Bi 2 O 3 and Eu 2 O 3 contained in the coloring component is an essential component for coloring the glass into a yellow color. If the content of the coloring component is less than 0.01%, the desired yellow glass cannot be obtained. Therefore, it is contained in an amount of 0.01% or more. It is preferably 0.05% or more, preferably 0.1% or more. Moreover, if the content exceeds 10%, the glass becomes unstable. Therefore, the content is 10% or less. It is preferably 8% or less, preferably 6% or less.

但是，CeO2之含量若超過3%則玻璃會變得不穩定。因此，CeO2之含量係令為3%以下。且宜為2.8%以下， 較佳則係2.5%以下。再者，Ce離子因在4價的狀態下呈現黄色，故宜以4價的狀態來添加，且以可氧化性來熔融。V2O5之含量若超過5%則玻璃會變得不穩定。因此，V2O5之含量係令為5%以下。且宜為4%以下，較佳則係3%以下。V離子因係在5價下呈現黄色，故以可氧化性來熔融為理想。Bi2O3之含量若超過10%則於熔融時會析出金屬鉍之膠體，因而呈現所要的黄色會變得困難。因此，Bi2O3之含量係令為10%以下。且宜為8%以下，較佳則係5%以下。Eu2O3之含量若超過3%則原料費會變高。因此，Eu2O3之含量係令為3%以下。且宜為2.5%以下，較佳則係2%以下。再者，於使用Eu2O3時，係以在還原側之熔融為宜。 However, if the content of CeO 2 exceeds 3%, the glass becomes unstable. Therefore, the content of CeO 2 is 3% or less. It is preferably 2.8% or less, preferably 2.5% or less. Further, since the Ce ion exhibits a yellow color in a tetravalent state, it is preferably added in a tetravalent state and melted by oxidizability. If the content of V 2 O 5 exceeds 5%, the glass becomes unstable. Therefore, the content of V 2 O 5 is 5% or less. It is preferably 4% or less, preferably 3% or less. Since the V ion has a yellow color at a valence of 5, it is desirable to melt it by oxidizability. When the content of Bi 2 O 3 exceeds 10%, the colloid of the metal ruthenium precipitates upon melting, and thus it becomes difficult to exhibit a desired yellow color. Therefore, the content of Bi 2 O 3 is 10% or less. It is preferably 8% or less, preferably 5% or less. If the content of Eu 2 O 3 exceeds 3%, the raw material cost becomes high. Therefore, the content of Eu 2 O 3 is 3% or less. It is preferably 2.5% or less, preferably 2% or less. Further, when Eu 2 O 3 is used, it is preferred to melt on the reduction side.

另外，於本實施形態中，只要在無損黄色系之著色的範圍內亦可使含有選自前述著色成分以外的著色成分MpOq(但是，在此，M係選自Co、Cu、Cr、Pr、Mn、Er、Ni、Nd、W、Rb、Sn及Ag中之至少一種，且p與q係M與O之原子比)中之至少一種。而該情況時，宜使與前述著色成分之合計含有率不超過10%。若含量超過10%則玻璃會變得不穩定。故宜為9%以下，較佳則係8%以下。 Further, in the present embodiment, the coloring component MpOq selected from the coloring components other than the coloring component may be contained in the range in which the coloring of the yellow color is not impaired (however, the M system is selected from Co, Cu, Cr, Pr, At least one of Mn, Er, Ni, Nd, W, Rb, Sn, and Ag, and at least one of p and q atomic ratios of M to O. In this case, the total content of the coloring component and the coloring component is preferably not more than 10%. If the content exceeds 10%, the glass becomes unstable.

藉由使含有B2O3可使耐氣候性提升。但是，若其含量小於0.1%則就提升耐氣候性而言有無法獲得有意義的效果之虞。因此，宜使含有0.1%以上。且較佳係0.5%以上， 特別理想的則係2%以上。又，若其含量超過12%則會發生因揮發造成的擦痕，而成品率會降低。因此，其含量係令為12%以下。且宜為10%以下，較佳則係8%以下。 Weather resistance can be improved by containing B 2 O 3 . However, if the content is less than 0.1%, there is a possibility that a satisfactory effect cannot be obtained in terms of improving weather resistance. Therefore, it is preferred to contain 0.1% or more. It is preferably 0.5% or more, and particularly preferably 2% or more.

藉由使含有K2O不但可使熔融性提升，同時還可增大化學強化中之離子交換速度。但是，若其含量小於0.1%則就提升熔融性而言可能無法獲得有意義的效果，或者是就提升離子交換速度而言有無法獲得有意義的效果之虞。因此，而宜使含有0.1%以上。且較佳係0.2%以上，特別理想的則係0.5%以上。又，若其含量超過5%則耐氣候性會降低。因此，其含量係令為5%以下。且宜為4.5%以下，較佳則係4%以下。 By containing K 2 O, not only the meltability can be improved, but also the ion exchange rate in chemical strengthening can be increased. However, if the content is less than 0.1%, a meaningful effect may not be obtained in terms of improving the meltability, or a meaningful effect may not be obtained in terms of increasing the ion exchange rate. Therefore, it is preferable to contain 0.1% or more. It is preferably 0.2% or more, and particularly preferably 0.5% or more.

Therefore, the content is 5% or less. It is preferably 4% or less, preferably 3% or less.

藉由使含有RO(但是，R係選自Sr、Ba及Ca中之 至少一種)可使熔融性提升。但就其另一面而言，因有使化學強化特性惡化之虞，故其添加應止於所需之最小限度，且其含量合計係以1%以下為宜，而以0.5%以下較佳。 By containing RO (however, R is selected from the group consisting of Sr, Ba, and Ca) At least one of them can improve the meltability.

However, if the content is less than 0.01%, there is a possibility that a meaningful effect cannot be obtained in terms of increasing the ion exchange rate. Therefore, it is preferred to contain 0.01% or more. It is preferably 0.05% or more, and particularly preferably 0.1% or more.

If the content is less than 55%, the stability as glass may be lowered, or the weather resistance may be lowered. Therefore, it contains 55% or more. And it is preferably 58% or more, and more preferably 60% or more. Moreover, if the content exceeds 80%, the viscosity of the glass increases and the meltability decreases. Therefore, the content is 80% or less. It is preferably 78% or less, preferably 75% or less.

Al2O3係使玻璃的耐氣候性提升之成分。若其含量小於3%則耐氣候性會降低。因此，而使含有3%以上。且宜為4%以上，而較佳係5%以上。又，若其含量超過16%，則玻璃的黏性會變高而均質的熔融會變得困難。因此，其含量係令為16%以下。且宜為14%以下，較佳則係12%以下。 Al 2 O 3 is a component that enhances the weather resistance of glass.

Therefore, it is preferred to contain 0.1% or more. It is preferably 0.2% or more, and particularly preferably 0.5% or more. Further, when the content exceeds 15%, cracks are likely to occur from the indentation when the surface of the glass is indented, and the strength of the glass is lowered.

And it is preferably 58% or more, and more preferably 60% or more. Moreover, if the content exceeds 80%, the viscosity of the glass increases and the meltability decreases. Therefore, the content is 80% or less. It is preferably 78% or less, preferably 75% or less.

Al2O3係使玻璃的耐氣候性提升之成分。若其含量小於3%則耐氣候性會降低。因此，而使含有3%以上。且宜為4%以上，而較佳係5%以上。又，若其含量超過16%，則玻璃的黏性會變高而均質的熔融會變得困難。因此，其含量係令為16%以下。且宜為14%以下，較佳則係12%以下。 Al 2 O 3 is a component that enhances the weather resistance of glass. If the content is less than 3%, the weather resistance will be lowered. Therefore, it contains 3% or more. And it is preferably 4% or more, and more preferably 5% or more. Moreover, when the content exceeds 16%, the viscosity of the glass becomes high, and homogeneous melting becomes difficult. Therefore, the content is such that it is 16% or less. It is preferably 14% or less, preferably 12% or less.

Na2O不但係使玻璃的熔融性提升之成分，同時亦係用以藉由離子交換而使形成壓縮應力層於玻璃表面上的必要成分。若其含量小於5%則熔融性會降低，且變得難以藉由離子交換而於玻璃表面上形成所需之壓縮應力層。因此，而使含有5%以上。且宜為6%以上，較佳則係8%以上。又，若其含量超過16%則耐氣候性會降低。因此，其含量係令為16%以下。且宜為15%以下，較佳則係14%以下。 Na 2 O is not only a component that enhances the meltability of the glass, but also an essential component for forming a compressive stress layer on the surface of the glass by ion exchange.

Therefore, it contains 5% or more. It is preferably 6% or more, preferably 8% or more. Moreover, if the content exceeds 16%, the weather resistance will be lowered. Therefore, the content is such that it is 16% or less. It is preferably 15% or less, preferably 14% or less.

Therefore, the content is 3% or less. It is preferably 2.8% or less, preferably 2.5% or less.

再者，藉由添加Fe2O3可促進離子交換，係推測因玻璃中存在著4配位之Fe3+，而使玻璃中之非架橋氧成為架橋氧，結果因負的電荷密度變低，而使Na+離子變得容易活動所致。 Furthermore, ion exchange can be promoted by the addition of Fe 2 O 3 , which is presumed to be due to the presence of 4-coordinated Fe 3+ in the glass, so that the non-bridging oxygen in the glass becomes bridging oxygen, resulting in a low negative charge density. And make Na + ions become easy to move.

If the content is less than 0.001%, the exposure resistance cannot be improved. Therefore, it is contained in an amount of 0.001% or more. It is preferably 0.01% or more, and preferably 0.02% or more. Moreover, when the content exceeds 3%, the crystallization tendency of the glass is promoted and the loss of transparency is caused.

作為著色成分之Cu2O及/或Ag2O係用以將玻璃著色成紅色系之色彩的必要成分。該著色成分之含量若小於0.001%則無法獲得所要的紅色玻璃。因此，而使含有0.001%以上。且宜為0.1%以上，較佳則係0.2%以上。又，若其含量超過6%則玻璃會變得不穩定。因此，其含量係令為6%以下。且宜為5%以下，較佳則係4%以下。 Cu 2 O and/or Ag 2 O, which are coloring components, are used to color the glass into an essential component of a red color. If the content of the coloring component is less than 0.001%, the desired red glass cannot be obtained. Therefore, it is contained in an amount of 0.001% or more.

Therefore, the content of Cu 2 O is 3% or less. It is preferably 2.8% or less, preferably 2.5% or less. Further, if the content of Ag 2 O exceeds 6%, the glass becomes unstable. Therefore, the content of Ag 2 O is 6% or less. It is preferably 5% or less, preferably 4% or less.

SnO及/或Sb2O3係發揮作為於後處理步驟之熱處 理中將為著色成分之Cu2O或Ag2O還原，而使析出Cu或Ag膠體之所謂熱還原劑之作用的成分。而兩者之合計含量若小於0.01%則有無法獲得所期望之作為熱還原劑的作用之虞。因此，兩者之合計含量係宜使含有0.01%以上。且較佳係0.1%以上，特別理想的則係0.3%以上。又，若含量超過5%則玻璃會變得不穩定而有容易失透明之虞。因此，其含量係宜令為5%以下。且較佳係4%以下，特別理想的則係3%以下。 The SnO and/or the Sb 2 O 3 system serves as a component which acts to reduce the Cu 2 O or Ag 2 O which is a coloring component in the heat treatment in the post-treatment step, and to precipitate a Cu or Ag colloid as a so-called thermal reducing agent.

Therefore, when SnO is contained, it is preferable to contain 0.05% or more. It is preferably 0.1% or more, and particularly preferably 0.2% or more. Moreover, if the content exceeds 3%, the glass becomes unstable and there is a tendency to lose transparency. Therefore, the content should preferably be 3% or less.

Therefore, when Sb 2 O 3 is contained, it is preferable to contain 0.05% or more. It is preferably 0.1% or more, and particularly preferably 0.2% or more. Moreover, if the content exceeds 5%, the glass becomes unstable and there is a tendency to lose transparency. Therefore, the content should preferably be 5% or less.

Therefore, it contains 5% or more. It is preferably 6% or more, preferably 8% or more. Moreover, if the content exceeds 20%, the weather resistance will be lowered. Therefore, the content is such that it is 20% or less. It is preferably 18% or less, preferably 16% or less.

Fe2O3係使玻璃中之離子的移動容易而促進離子交換的成分。若其含量小於0.001%則無法獲得促進離子交換效果。因此，而使含有0.001%以上。且宜為0.01%以上，較佳則係0.03%以上。又，若其含量超過3%則玻璃會變得不穩定而容易發生失透明。因此，其含量係令為3%以下。且宜為2.8%以下，較佳則係2.5%以下。 Fe 2 O 3 is a component that facilitates the movement of ions in the glass and promotes ion exchange. If the content is less than 0.001%, the effect of promoting ion exchange cannot be obtained. Therefore, it is contained in an amount of 0.001% or more. It is preferably 0.01% or more, preferably 0.03% or more. Moreover, if the content exceeds 3%, the glass becomes unstable and the loss of transparency tends to occur. Therefore, the content is 3% or less. It is preferably 2.8% or less, preferably 2.5% or less.

再者，藉由添加Fe2O3可促進離子交換，係推測因玻璃中存在著4配位之Fe3+，而使玻璃中之非架橋氧成為架橋氧，結果因負的電荷密度變低，而使Na+離子變得容易活動所致。 Furthermore, ion exchange can be promoted by the addition of Fe 2 O 3 , which is presumed to be due to the presence of 4-coordinated Fe 3+ in the glass, so that the non-bridging oxygen in the glass becomes bridging oxygen, resulting in a low negative charge density. And make Na + ions become easy to move.

Fe2O3係依據Fe離子之價態來賦予玻璃黄色或者係綠色的色彩。於Fe2+的情況時係綠色~藍綠色，而於Fe3+的情況時則係成為黄色。本發明之大特徵，即對於化學強化的促進係以Fe3+之狀態為宜，且以可氧化性來熔融為理想，但因通常在玻璃中Fe2+與Fe3+係共存的，故無法全部皆為Fe3+之狀態。因此，於Fe2O3之含量多時係會有出現少量存在之Fe2+的顏色的情況，此時，為了顯示出呈現綠色， 亦可將Fe2O3與前述之綠色的著色劑併用。由於Fe3+而呈現出的黄色雖淡，但以相同之想法而言亦可將Fe2O3與前述之黄色的著色劑併用。 Fe 2 O 3 imparts a yellowish or greenish color depending on the valence state of the Fe ions. Fe-based green to blue-green when the case ~ 2+, Fe 3+ and when the circumstances of the system becomes yellow. The great feature of the present invention is that the promotion of chemical strengthening is preferably in the state of Fe 3+ and is preferably melted by oxidizability, but since Fe 2+ and Fe 3+ are usually coexisted in the glass, Not all of them are in the state of Fe 3+ . Therefore, when the content of Fe 2 O 3 is large , a small amount of Fe 2+ may be present. In this case, in order to exhibit green color, Fe 2 O 3 may be used in combination with the green coloring agent described above. . Although the yellow color exhibited by Fe 3+ is light, Fe 2 O 3 may be used in combination with the aforementioned yellow coloring agent in the same manner.

TiO2係提高玻璃之耐曝晒作用性，且同時為有提高因其他之有色離子而產生之著色效果的成分。若其含量小於0.001%則無法使耐曝晒作用性提升。因此，而使含有0.001%以上。且宜為0.01%以上，較佳則係0.02%以上。又，若其含量超過3%，則會促進玻璃之結晶化傾向而容發生失透明。因此，其含量係令為3%以下。且宜為2.8%以下，較佳則係2.5%以下。 TiO 2 improves the anti-exposure effect of glass and at the same time has a coloring effect which enhances the coloring effect due to other colored ions. If the content is less than 0.001%, the exposure resistance cannot be improved. Therefore, it is contained in an amount of 0.001% or more. It is preferably 0.01% or more, and preferably 0.02% or more. Moreover, when the content exceeds 3%, the crystallization tendency of the glass is promoted and the loss of transparency is caused. Therefore, the content is 3% or less. It is preferably 2.8% or less, preferably 2.5% or less.

著色成分之MpOq(但是，M係選自Co、Cu、V、Cr、Pr、Ce、Bi、Eu、Mn、Er、Ni、Nd、W、Rb、Sn及Ag中之至少一種，且p與q係M與O之原子比)係用以將玻璃著色成所需之色彩的成分，而對前述第7實施形態之化學強化用玻璃，藉由適當地選擇著色成分而可獲得例如藍色系、綠色系、黄色系、紫色~粉紅色系及紅色系等之著色玻璃。 MpOq of the coloring component (however, M is selected from at least one of Co, Cu, V, Cr, Pr, Ce, Bi, Eu, Mn, Er, Ni, Nd, W, Rb, Sn, and Ag, and p is The atomic ratio of the M system to the O is a component for coloring the glass into a desired color, and the glass for chemical strengthening according to the seventh embodiment can be obtained, for example, by appropriately selecting a coloring component. Colored glass such as green, yellow, purple, pink, and red.

具體而言，例如使用選自Co3O4及CuO中之至少一種成分，則可獲得藍色系之著色玻璃。使用選自V2O5、Cr2O3、CuO及Pr6O11中之至少一種成分，則可獲得綠色系之著色玻璃。使用選自CeO2、V2O5、Bi2O3及Eu2O3中之至少一種成分，則可獲得黄色系之著色玻璃。使用選自MnO2、Er2O3、NiO、Nd2O3及WO3中之至少一種成分，則可獲得紫色~粉紅色系之著色玻璃。而使用選自Cu2O及 Ag2O中之至少一種成分，則可獲得紅色系之著色玻璃。 Specifically, for example, a blue-based colored glass can be obtained by using at least one component selected from the group consisting of Co 3 O 4 and CuO.

When at least one component selected from the group consisting of CeO 2 , V 2 O 5 , Bi 2 O 3 and Eu 2 O 3 is used, a yellow colored glass can be obtained. When at least one component selected from the group consisting of MnO 2 , Er 2 O 3 , NiO, Nd 2 O 3 and WO 3 is used, a purple-pink colored glass can be obtained. When at least one component selected from the group consisting of Cu 2 O and Ag 2 O is used, a red colored glass can be obtained.

若前述MpOq之著色成分的含量小於0.001%則會因玻璃之著色變得極淡，而若不將玻璃增厚則無法作為有色來辨識，故為使擁有作為著色框體之設計性，而產生必須將厚度設計得相當厚的情況。因此，而使含有0.001%以上。且宜為0.05%以上，較佳則係0.1%以上。又，若其含量超過10%則玻璃會變得不穩定。因此，其含量係令為10%以下。且宜為8%以下，較佳則係5%以下。 If the content of the color component of the above MpOq is less than 0.001%, the color of the glass becomes extremely light, and if the glass is not thickened, it cannot be recognized as a colored color, so that the design is made as a colored frame. The thickness must be designed to be quite thick. Therefore, it is contained in an amount of 0.001% or more. It is preferably 0.05% or more, preferably 0.1% or more. Moreover, if the content exceeds 10%, the glass becomes unstable. Therefore, the content is 10% or less. It is preferably 8% or less, preferably 5% or less.

藉由使含有CaO可使熔融性提升。但是，若其含量小於1%則就提升熔融性而言有無法獲得有意義的效果之虞。因此，宜使含有1%以上。且較佳係3%以上，特別理想的則係4%以上。又，若其含量超過15%則耐氣候性會降低。因此，其含量係令為15%以下。且宜為14%以下，較佳則係12%以下。 The meltability can be improved by containing CaO. However, if the content is less than 1%, there is a possibility that a meaningful effect cannot be obtained in terms of improving the meltability. Therefore, it is preferable to contain 1% or more. It is preferably 3% or more, and particularly preferably 4% or more. Moreover, if the content exceeds 15%, the weather resistance will be lowered. Therefore, the content is made 15% or less. It is preferably 14% or less, preferably 12% or less.

However, if the content is less than 0.1%, there is a possibility that a satisfactory effect cannot be obtained in terms of improving weather resistance. Therefore, it is preferred to contain 0.1% or more. It is preferably 0.5% or more, and particularly preferably 2% or more. Further, if the content exceeds 12%, scratches due to volatilization occur, and the yield is lowered. Therefore, the content is such that it is 12% or less.

藉由使含有K2O不但可使熔融性提升，同時還可增大化學強化中之離子交換速度。但是，若其含量小於0.1%則就提升熔融性而言可能無法獲得有意義的效果，或者是就提升離子交換速度而言有無法獲得有意義的效果之虞。因此，宜使含有0.1%以上。且較佳係0.2%以上，特別理想的則係0.5%以上。又，若其含量超過8%則耐氣候性會降低。因此，其含量係令為8%以下。且宜為6%以下，較佳則係4%以下。 By containing K 2 O, not only the meltability can be improved, but also the ion exchange rate in chemical strengthening can be increased. However, if the content is less than 0.1%, a meaningful effect may not be obtained in terms of improving the meltability, or a meaningful effect may not be obtained in terms of increasing the ion exchange rate. Therefore, it is preferred to contain 0.1% or more. It is preferably 0.2% or more, and particularly preferably 0.5% or more. Moreover, if the content exceeds 8%, the weather resistance will be lowered. Therefore, the content is 8% or less. It is preferably 6% or less, preferably 4% or less.

Therefore, the content is 5% or less. It is preferably 4% or less, preferably 3% or less.

藉由使含有RO(但是，R係選自Sr、Ba及Mg中之至少一種)可使熔融性提升。但就其另一面而言，因有使化學強化特性惡化之虞，故其添加應止於所需之最小限度，且其含量合計係以1%以下為宜，而以0.5%以下較佳。 The meltability can be improved by including RO (however, R is at least one selected from the group consisting of Sr, Ba, and Mg). On the other hand, since the chemical strengthening property is deteriorated, the addition thereof should be kept to a minimum required, and the total content thereof is preferably 1% or less, and preferably 0.5% or less.

藉由使含有ZrO2可增大離子交換速度。但是，若 其含量小於0.01%則就提升離子交換速度而言有無法獲得有意義的效果之虞。因此，宜使含有0.01%以上。且較佳係0.05%以上，特別理想的則係0.1%以上。又，若其含量超過5%則熔融性會降低而有成為未熔融物而殘留於玻璃中之虞。因此，其含量係令為5%以下。且宜為4%以下，較佳則係3%以下。 The ion exchange rate can be increased by including ZrO 2 . However, if the content is less than 0.01%, there is a possibility that a meaningful effect cannot be obtained in terms of increasing the ion exchange rate.

於本實施形態之化學強化玻璃中，更可依所需而使其含有SO3、SnO及Sb2O3。 In the chemically strengthened glass of the present embodiment, SO 3 , SnO, and Sb 2 O 3 may be contained as needed.

SO3係作為澄清劑來發揮作用之成分。但是，若其含量小於0.01%則有無法獲得所期望之澄清作用之虞。因此，使含有SO3時，宜使含有0.01%以上。且較佳係0.03%以上，特別理想的則係0.05%以上。又，若其含量超過1%則反而會變為氣泡之產源，而有玻璃之燒穿變慢、氣泡個數增加之虞。因此，其含量係令為1%以下。且較佳係0.8%以下，特別理想的則係0.6%以下。 SO 3 is a component that functions as a clarifying agent.

Therefore, the content is preferably 1% or less. It is preferably 0.8% or less, and particularly preferably 0.6% or less.

於使著色為紅色系的情況時，SnO係具有於後處理步驟之熱處理中作為將Cu2O或Ag2O還原，而使析出Cu或Ag膠體之所謂的熱還原劑的作用。但是，若其含量小於0.05%則有無法獲得所期望之作為熱還原劑的作用之虞。因此，使含有SnO時宜使含有0.05%以上。且較佳係0.1%以上，特別理想的則係0.2%以上。又，若其含量超過3%則玻璃會變得不穩定而有容易失透明之虞。因此，其含量係宜令為3%以下。且較佳係2.8%以下，特別理想的則係2.5%以下。 In the case where the coloring is red, the SnO system functions as a so-called thermal reducing agent for reducing Cu 2 O or Ag 2 O to precipitate Cu or Ag colloid in the heat treatment in the post-treatment step.

於使著色為紅色系的情況時，Sb2O3係與SnO相 同具有作為熱還原劑的作用。但是，若其含量小於0.05%則有無法獲得所期望之作為熱還原劑的作用之虞。因此，使含有Sb2O3時，宜使含有0.05%以上。且較佳係0.1%以上，特別理想的則係0.2%以上。又，若其含量超過5%則玻璃會變得不穩定而有變得容易失透明之虞。因此，其含量係宜令為5%以下。且較佳係3%以下，特別理想的則係1%以下。 When the coloring is red, the Sb 2 O 3 system functions as a thermal reducing agent in the same manner as SnO. However, if the content is less than 0.05%, the desired effect as a thermal reducing agent cannot be obtained. Therefore, when Sb 2 O 3 is contained, it is preferable to contain 0.05% or more. It is preferably 0.1% or more, and particularly preferably 0.2% or more. Moreover, if the content exceeds 5%, the glass becomes unstable and it becomes easy to lose transparency. Therefore, the content should preferably be 5% or less. It is preferably 3% or less, and particularly preferably 1% or less.

另外，因Sb2O3係環境危害性物質，故熱還原劑宜使用SnO。 In addition, since Sb 2 O 3 is an environmentally hazardous substance, it is preferable to use SnO as a thermal reducing agent.

本實施形態之化學強化用玻璃特別是藉由使其含有Fe2O3及TiO2可具備優異之耐曝晒作用性，同時還可藉由施行化學強化處理而於表面上形成具有充分深度及表面壓縮應力之壓縮應力層，故可獲得業經著色之高強度的化學強化玻璃。所獲得之化學強化玻璃作為構成電子機器之外裝的玻璃框體的材料是有効用的。 In particular, the glass for chemical strengthening of the present embodiment can have excellent anti-exposure action by containing Fe 2 O 3 and TiO 2 , and can form a sufficient depth and surface on the surface by performing chemical strengthening treatment. By compressing the compressive stress layer of the stress, it is possible to obtain a high-strength chemically strengthened glass which is colored. The obtained chemically strengthened glass is effective as a material constituting a glass frame which is externally mounted on an electronic device.

另外，本實施形態之化學強化用玻璃的製造方法係無特別限定，譬如，適量調配各種的原料，於加熱至約1500~1600℃且熔融之後，藉由消泡及攪拌等使其均質化，並利用周知之下拉法、壓製法等來成形為板狀，或者係進行澆鑄而成形為磚塊狀，並且於緩冷卻後切割為所需之尺寸、且依所需施以研磨加工而製造。 In addition, the method for producing the glass for chemical strengthening of the present embodiment is not particularly limited.

又，將本實施形態之化學強化用玻璃進行化學強化之方法，只要是可將玻璃表層之Na2O與熔融鹽中之K2O進行離子交換之方法則無特別之限定，例如可用使玻璃板或者係玻璃成形品浸漬於已加熱至400~550℃之硝酸鉀 (KNO3)熔融鹽中2~20個小時之方法等。 Further, the method of chemically strengthening the glass for chemical strengthening of the present embodiment is not particularly limited as long as it can ion-exchange the Na 2 O of the glass surface layer with K 2 O in the molten salt, and for example, glass can be used. The plate or the glass molded article is immersed in a molten salt of potassium nitrate (KNO 3 ) which has been heated to 400 to 550 ° C for 2 to 20 hours.

△T(%)=[(T0-T1)/T0]×100 △T(%)=[(T0-T1)/T0]×100

(此處，T1：使400W高壓水銀燈的光以間隔距離15cm照射兩面業經鏡面光學研磨且厚度為2mm之化學強化用玻璃的研磨面50小時後，分光透射率曲線中波長380nm~780nm的平均透射率；T0：光照射前之分光透射率曲線中，波長380nm~780nm的平均透射率) (Here, T1: The average transmission of the wavelength of 380 nm to 780 nm in the spectral transmittance curve after 50 hours of irradiation of the surface of the chemical strengthening glass with a mirror surface optical polishing and a thickness of 2 mm by the light of a 400 W high-pressure mercury lamp at a distance of 15 cm. Rate; T0: average transmittance of a wavelength of 380 nm to 780 nm in a spectral transmittance curve before light irradiation)

該透射率劣化度係評估化學強化用玻璃之耐曝晒作用性之指標。 The degree of deterioration of the transmittance is an index for evaluating the resistance to exposure of the glass for chemical strengthening.

(玻璃框體之實施形態) (embodiment of glass frame)

接著，將就本發明之玻璃框體之實施形態予以說明。 Next, an embodiment of the glass casing of the present invention will be described.

本實施形態之玻璃框體係用於行動電話等之可攜帶使用之電子機器的外裝之框體，且係由將前述之化學強化用玻璃經化學強化而獲得的化學強化玻璃所構成。 The glass frame system of the present embodiment is used for an exterior frame of an electronic device that can be used for mobile phones and the like, and is composed of chemically strengthened glass obtained by chemically strengthening the above-mentioned chemical strengthening glass.

化學強化用玻璃之化學強化，舉例而言，係藉由使玻璃板浸漬於已加熱至400~550℃之硝酸鉀(KNO3)熔融鹽中2~20個小時來進行，但並非特別侷限於該方法，只要是可將玻璃表層之Na2O與熔融鹽中之K2O進行離子交換之方法即可。 The chemical strengthening of the glass for chemical strengthening is carried out, for example, by immersing the glass plate in a molten salt of potassium nitrate (KNO 3 ) heated to 400 to 550 ° C for 2 to 20 hours, but is not particularly limited. the method, as long as the surface layer of the glass may be Na 2 O to a method of ion-exchanged with molten salt of K 2 O.

透過施行所述之化學強化處理，可於化學強化玻璃表面上形成壓縮應力層。於本實施形態中，壓縮應力層之深度係宜為30μm以上，且以40μm以上較佳。若深度小於 30μm則有無法具備對行動電話等之電子機器的框體所要求的強度之虞。但是，若壓縮應力層太深的話則內部拉伸應力會變大，而破壞時的衝擊就會變大。即，已知若內部拉伸應力大則於玻璃破壞時會有變成細碎片而粉碎地飛散的傾向而危險性會增高。依據本案發明人等之實驗結果，已清楚明白就厚度2mm以下的玻璃而言，若其壓縮應力層的深度超過70μm則破壞時之飛散會變得顯著。因此，至少在化學強化玻璃之厚度為2mm以下的情況時，壓縮應力層之深度係以令為70μm以下為宜。且較佳係60μm以下，特別理想的則係50μm以下。另外，化學強化玻璃係亦可使其表面進行研磨，而於該情況時，於研磨後係宜滿足上述要件。 A compressive stress layer can be formed on the surface of the chemically strengthened glass by performing the chemical strengthening treatment described above. In the present embodiment, the depth of the compressive stress layer is preferably 30 μm or more, and more preferably 40 μm or more. If the depth is less than At 30 μm, there is no need to have the strength required for the casing of an electronic device such as a mobile phone. However, if the compressive stress layer is too deep, the internal tensile stress becomes large, and the impact at the time of destruction becomes large. In other words, it is known that when the internal tensile stress is large, the glass tends to become fine fragments and pulverize and scatter when the glass is broken, and the risk is increased. According to the experimental results of the inventors of the present invention, it is clear that when the depth of the compressive stress layer exceeds 70 μm, the scattering of the glass having a thickness of 2 mm or less becomes remarkable. Therefore, at least when the thickness of the chemically strengthened glass is 2 mm or less, the depth of the compressive stress layer is preferably 70 μm or less. It is preferably 60 μm or less, and particularly preferably 50 μm or less. Further, the chemically strengthened glass system may be subjected to polishing of the surface thereof, and in this case, it is preferable to satisfy the above requirements after the polishing.

此處，「壓縮應力層之深度」係指經離子交換之鹼金屬離子(鉀離子或鈉離子)擴散至玻璃之深度，舉例而言可使用利用了光彈性分析(photoelastic analysis)法之表面應力計來測定。 Here, the "depth of the compressive stress layer" means the depth at which the ion-exchanged alkali metal ion (potassium ion or sodium ion) diffuses to the glass, and for example, a surface stress using a photoelastic analysis method can be used. Calculated.

又，壓縮應力層係以表面壓縮應力為550MPa以上者為宜，且以700MPa以上較佳。若表面壓縮應力小於550MPa則有無法具備對行動電話等之電子機器的框體所要求的強度之虞。表面壓縮應力係與壓縮應力層之深度相同，譬如可使用利用了光彈性分析法之表面應力計來測定。 Further, the compressive stress layer is preferably a surface compressive stress of 550 MPa or more, and more preferably 700 MPa or more. If the surface compressive stress is less than 550 MPa, the strength required for the casing of an electronic device such as a mobile phone cannot be obtained. The surface compressive stress is the same as the depth of the compressive stress layer, and can be measured, for example, using a surface stress meter using photoelastic analysis.

另外，構成框體之化學強化玻璃其厚度係至少宜為0.5mm以上，即以最薄的部分而言其厚度係以0.5mm以上為宜，且以0.8mm以上較佳。若化學強化玻璃之厚度小於0.5mm，則即便為已使用了化學強化用玻璃的情況時亦會 有無法具備對行動電話等之電子機器的框體所要求的強度之虞。 Further, the thickness of the chemically strengthened glass constituting the frame is preferably at least 0.5 mm, that is, the thickness of the thinnest portion is preferably 0.5 mm or more, and more preferably 0.8 mm or more. If the thickness of the chemically strengthened glass is less than 0.5 mm, even if the chemical strengthening glass is used, There is no need to have the strength required for the frame of an electronic device such as a mobile phone.

以上，雖說明了本發明之實施形態，但本發明並不侷限於上述記載內容，只要在不離本發明之範疇內所有的變形或變更是可能的。 The embodiments of the present invention have been described above, but the present invention is not limited to the above description, and all modifications and changes may be made without departing from the scope of the invention.

[色度] [chroma]

將於各例所獲得之板狀的化學強化用玻璃當作為測定試料。對於該測定試料以紫外線可見光近紅外線分光光度計(日本分光股份有限公司製，V-570)測定透射率，並根據JIS Z8722：2000(色彩之測定方法-反射及透射物體色)將其 資料換算成CIE 1931XYZ表色度系統。 The plate-shaped chemical strengthening glass obtained in each example was used as a measurement sample. The measurement sample was measured for transmittance by an ultraviolet-visible near-infrared spectrophotometer (manufactured by JASCO Corporation, V-570), and was measured in accordance with JIS Z8722:2000 (method of color measurement - reflection and transmission of object color). The data is converted into the CIE 1931XYZ table chroma system.

[曝晒作用] [Exposure effect]

將於例1-14(實施例)及例1-15(比較例)所得之板狀的化學強化用玻璃當作為試料。使400W高壓水銀燈的光從距離15cm的位置照射該等各測定試料的研磨面50小時後，測定波長380nm~780nm的平均透射率T1，並且藉由下式算出自初期(光照射前)之波長380nm~780nm的平均透射率T0之劣化度△T。另外，對於透射率之測定係使用了紫外線可見光近紅外線分光光度計(日本分光股份有限公司製，V-570)。 The plate-shaped chemical strengthening glass obtained in Examples 1-14 (Examples) and Examples 1-15 (Comparative Examples) was used as a sample. The light of the 400 W high-pressure mercury lamp was irradiated to the polishing surface of each of the measurement samples at a distance of 15 cm, and the average transmittance T1 of the wavelength of 380 nm to 780 nm was measured, and the wavelength from the initial stage (before the light irradiation) was calculated by the following formula. The deterioration degree ΔT of the average transmittance T0 of 380 nm to 780 nm. Further, for the measurement of the transmittance, an ultraviolet visible light near-infrared spectrophotometer (manufactured by JASCO Corporation, V-570) was used.

In addition, in Fig. 1, (a) is the measurement result of the example 1-14 (Example), and (b) is the measurement result of the Example 1-15 (comparative example).

由表6及第1圖可明白，藉由使玻璃含有預定量之TiO2成分，則玻璃之耐曝晒作用性會提升。因此，將本發明之化學強化用玻璃作為框體材料來使用時，可長期維持當初之著色狀態，而不會有因顏色的變化而造成設計性受損的情形。 As can be understood from Table 6 and Fig. 1, by making the glass contain a predetermined amount of the TiO 2 component, the glass exposure resistance is improved. Therefore, when the glass for chemical strengthening of the present invention is used as a frame material, the original coloring state can be maintained for a long period of time without causing damage to the design due to a change in color.

[壓縮應力層之深度及表面壓縮應力] [depth of compressive stress layer and surface compressive stress]

將於例2-1(實施例)中所得之板狀的化學強化用玻璃浸 漬於425℃之KNO3熔融鹽(100%)中6小時以進行化學強化處理並且將之當作為試料。又，為了做比較，而對在例2-9(比較例)中所得之板狀的化學強化用玻璃進行相同之化學強化處理並且將之當作為試料。另外，例2-9的玻璃係除了未摻混Fe2O3成分以外係與例2-1為同一組成的玻璃。 The plate-shaped chemical strengthening glass obtained in Example 2-1 (Example) was immersed in a KNO 3 molten salt (100%) at 425 ° C for 6 hours for chemical strengthening treatment and used as a sample. Moreover, for the purpose of comparison, the plate-shaped chemical strengthening glass obtained in Example 2-9 (Comparative Example) was subjected to the same chemical strengthening treatment and used as a sample. Further, the glass of Example 2-9 was a glass having the same composition as that of Example 2-1 except that the Fe 2 O 3 component was not blended.

針對該等化學處理後之測定試料，使用表面應力計(折原製作所有限公司製，FSM-6000LE)測定了壓縮應力層的深度(單位：μm)及表面壓縮應力(單位：MPa)。並將結果示於表7。 For the measurement samples after the chemical treatment, the depth (unit: μm) and the surface compressive stress (unit: MPa) of the compressive stress layer were measured using a surface stress meter (FSM-6000LE, manufactured by Ohara Seisakusho Co., Ltd.). The results are shown in Table 7.

由表7可知藉由使玻璃含有預定量之Fe2O3成分，則化學處理後的玻璃強度會變高。因此，本發明之化學強化用玻璃係可適用於作為尋求高強度之行動電話等之電子機器的框體用玻璃。 As is clear from Table 7, when the glass contains a predetermined amount of the Fe 2 O 3 component, the strength of the glass after the chemical treatment becomes high.
